| Make sure you have done the steps described at [[Initial_instructions_for_2010| the initial instructions for the 2010 Synthesis Workshop Tutorials]].

| |
| | |
| == Overview ==
| |
| | |
| This CASA Guide describes the imaging of the supernova remnant [http://simbad.u-strasbg.fr/simbad/sim-id?Ident=G55.7+3.4&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id G55.7+3.4.]. The data were taken on August 23, 2010, in the first D-configuration for which the new wide-band capabilities of the WIDAR correlator were available. The 8-hour-long observation includes all available 1 GHz of bandwidth in L-band, from 1-2 GHz in frequency.
| |
| | |
| The measurement set (MS) which provides a starting point for this Guide has been imported from the SDM file set and time-averaged to 10 seconds. Both of these options are available from the NRAO data archive, and since this operation can be relatively time-consuming, the imported, time-averaged dataset is being provided. The original data set can be found [[https://archive.nrao.edu/archive/ArchiveQuery?PASSWD=&QUERYTYPE=ARCHIVE&PROTOCOL=HTML&SORT_PARM=Starttime&SORT_ORDER=Asc&MAX_ROWS=NO+LIMIT&SORT_PARM2=Starttime&SORT_ORDER2=Asc&QUERY_ID=9999&QUERY_MODE=Prepare+Download&LOCKMODE=PROJECT&SITE_CODE=AOC&DBHOST=CHEWBACCA&WRITELOG=0&PROJECT_CODE=&SEGMENT=&OBSERVER=&ARCHIVE_VOLUME=AB1345_sb1800808_1.55431.004049953706&TIMERANGE1=&TIMERANGE2=&SOURCE_ID=&SRC_SEARCH_TYPE=SIMBAD+or+NED+Resolver&CALIB_TYPE=ALL+Srcs&CENTER_RA=&LONG_RANGE=&FRAME=Equatorial&CENTER_DEC=&LAT_RANGE=&EQUINOX=J2000&SRAD=10.0%27&MIN_EXPOSURE=&OBS_BANDS=ALL&TELESCOPE=EVLA&OBS_MODE=ALL&CORR_MODE=ALL&TELESCOPE_CONFIG=ALL&OBS_POLAR=ALL&SUBARRAY=ALL&OBSFREQ1=&DATATYPE=ALL&OBSBW1=&ARCHFORMAT=ALL&SUBMIT=Submit+Query here]]; note that it is 170 GB in raw form.
| |
| | |
| Averaging to 10 seconds and the removal of some scans which are not used in this tutorial reduces the size of the data set to around 14 GB; the addition of columns for model and corrected data (known as "scratch columns") returns it to 43 GB, which is the size of the MS which will be used here.

| | |
| Start CASA by typing <tt>casapy-stable</tt> on the command line. If you have not used CASA before, some helpful tips are available on the [[Getting Started in CASA]] page.
| |
| | |
| As a first step, use {{listobs}} to have a look at the MS:
| |
| | |
| <source lang="python">
| |
| # In CASA | |
| listobs('G55.7+3.4_10s.ms')
| |
| </source>
| |
| | |
| The logger output will look like this:

| We can see that there are three sources in this observation:
| |
| | |
| * J1925+2106, field ID 1: the phase calibrator;
| |
| * G55.7+3.4, field ID 2: the supernova remnant;
| |
| * 0542+498=3C147, field ID 3: the flux and bandpass calibrator.
| |
| | |
| We can also see that these sources have associated "scan intents", which indicate their function in the observation, and may be selected on using CASA tasks. In particular,
| |
| | |
| * CALIBRATE_PHASE indicates that this is a scan to be used for gain calibration;
| |
| * OBSERVE_TARGET indicates that this is the science target;
| |
| * CALIBRATE_AMPLI indicates that this is to be used for flux calibration; and
| |
| * CALIBRATE_BANDPASS indicates that these scans are to be used for bandpass calibration.
| |
| | |
| Note that 3C147 is to be used for both flux and bandpass calibration.
| |
| | |
| We can see the antenna configuration for this observation using {{plotants}}:
| |
| | |
| <source lang="python">
| |
| # In CASA
| |
| plotants('G55.7+3.4_10s.ms')
| |
| </source>
| |
| | |
| [[Image:plotAnts.png|200px|thumb|right|plotants image]]
| |
| | |
| This shows that antennas ea01, ea18, and ea03 were on the extreme ends of the west, north, and east arms, respectively. The antenna position diagram is particularly useful in determining if a co-located set of antennas is affected, which can help with flagging.
| |
| | |
| We may also inspect the raw data using {{plotms}}. To start with, let's look at a subset of scans on the supernova remnant:
| |
| | |
| <source lang="python">
| |
| # In CASA
| |
| plotms(vis='G55.7+3.4_10s.ms', scan='30,75,120,165,190,235,303',
| |
| antenna='ea24', xaxis='freq', yaxis='amp', coloraxis='spw',
| |
| iteraxis='scan', correlation='rr,ll')
| |
| </source>
| |
| | |
| The <tt>coloraxis</tt> parameter indicates that a different color will be assigned to each spectral window, and the <tt>iteraxis</tt> parameter tells plotms to display a new plot for each scan. We have chosen only one antenna (ea24) and just the right and left circular polarizations (without the cross-hand terms) to reduce the amount of data in the selection, One can flip through these plots using the green arrows located at the bottom of the plotting gui: the double-left arrow will display the very first plot in the set, the single left arrow will go back one plot, and the right arrows have similar behavior for moving forward in the set.
| |
| | |
| [[Image:PlotMS1.png|200px|thumb|right|plotms image]]
| |
| | |
| Flipping through the scans, it's clear that there is significant time- and frequency-variable RFI present in this observation. Since this is L-band data taken in the most compact EVLA configuration ("D"), this comes as no surprise. However, it also poses one of the greatest challenges for obtaining a good image.
| |
| | |
| In particular, we can see that two spectral windows (SPWs) are quite badly affected. To determine which these are, click in the "Mark Regions" tool at the bottom of the gui (the open box with a green "plus" sign), and use the mouse to select a few of the highest-amplitude points in each of these SPWs. Click on the "Locate" button (magnifying glass), and information associated with the selected points will be displayed in the logger window:

| We can see that SPWs 1 and 4 are among the worst affected by RFI. At this point, feel free to play around a bit more with {{plotms}}; you might try experimenting with different axes for iteration (under the "Iter" left-hand tab), different data selection parameters (under "Data"), different axes ("Axes"), or different averaging techniques (under "Data").

| == A priori calibration and flagging ==
| |
| | |
| Before we proceed with further processing, we should check the observation log to see if there were any issues noted during the run that need to be addressed. The observing log file is linked to the [[https://archive.nrao.edu/archive/ArchiveQuery?PASSWD=&QUERYTYPE=ARCHIVE&PROTOCOL=HTML&SORT_PARM=Starttime&SORT_ORDER=Asc&MAX_ROWS=NO+LIMIT&SORT_PARM2=Starttime&SORT_ORDER2=Asc&QUERY_ID=9999&QUERY_MODE=Prepare+Download&LOCKMODE=PROJECT&SITE_CODE=AOC&DBHOST=CHEWBACCA&WRITELOG=0&PROJECT_CODE=&SEGMENT=&OBSERVER=&ARCHIVE_VOLUME=AB1345_sb1800808_1.55431.004049953706&TIMERANGE1=&TIMERANGE2=&SOURCE_ID=&SRC_SEARCH_TYPE=SIMBAD+or+NED+Resolver&CALIB_TYPE=ALL+Srcs&CENTER_RA=&LONG_RANGE=&FRAME=Equatorial&CENTER_DEC=&LAT_RANGE=&EQUINOX=J2000&SRAD=10.0%27&MIN_EXPOSURE=&OBS_BANDS=ALL&TELESCOPE=EVLA&OBS_MODE=ALL&CORR_MODE=ALL&TELESCOPE_CONFIG=ALL&OBS_POLAR=ALL&SUBARRAY=ALL&OBSFREQ1=&DATATYPE=ALL&OBSBW1=&ARCHFORMAT=ALL&SUBMIT=Submit+Query archive web page]] for this observation (at far right; under "logs etc."). Looking at the log, we can see that antenna ea07 may need a position correction, and antennas ea06, ea17, ea20, and ea26 did not have L-band receivers installed at the time and should be flagged.
| |
| | |
| === Antenna position correction ===
| |
| | |
| Correcting the position of an antenna is done with the task {{gencal}}. This is important, because the observed visibilities are a function of <math>u</math> and <math>v</math>. If an antenna's position is incorrect, then <math>u</math> and <math>v</math> will be calculated incorrectly, and there will be errors in any image derived from the data. (These corrections could also be determined later by a baseline-based calibration incorporating the <math>b_{ij}</math> term from the equation above, but since they are known <i>a priori</i> it makes sense to incorporate them now.)
| |
| | |
| Any corrections can be ascertained from the [http://www.vla.nrao.edu/astro/archive/baselines/ EVLA/VLA Baseline Corrections] site. For future reference, be sure to read to the bottom of that document to see how to calculate the additive corrections. Fortunately, the current case is simple as there is only a single correction for antenna ea07.
| |
| | |
| To find the necessary x, y, and z-offsets to perform the position correction, first select the year "2010" for the EVLA baseline corrections. From the log, we know that the observation was performed on 23 August 2010; looking at the position table, we can see that antenna ea07 was moved on 5 August, but that the updated position was not included in the online system's database until 15 September. Therefore, we need to record the x, y, and z-position information for this antenna and input it into {{gencal}} to create a position-correction calibration table:
| |
| | |
| <source lang="python">
| |
| # In CASA
| |
| gencal(vis='G55.7+3.4_10s.ms', caltable='G55.7+3.4_10s.pos',
| |
| caltype='antpos', antenna='ea07',
| |
| parameter=[0.0087, 0.0137, 0.0000])
| |
| </source>
| |
| | |
| We will carry this table throughout the calibration to account for the revised antenna position for ea07.
| |
| | |
| === Flagging non-operational antennas ===
| |
| | |
| In addition to updating the position for antenna ea07, we have to flag antennas ea06, ea17, ea20, and ea26, since these did not have working L-band receivers at the time of observation. We do this with the task {{flagdata}}:
| |
| | |
| <source lang="python">
| |
| # In CASA
| |
| flagdata(vis='G55.7+3.4_10s.ms', mode='manualflag',
| |
| antenna='ea06,ea17,ea20,ea26')
| |
| </source>
| |
| | |
| Note that the first thing {{flagdata}} does is create a backup flag file, in this case named "manualflag_1". This flag file contains a copy of the flags present in the MS prior to the requested flagging operation. Since these flag files take up a fair amount of space (in this particular case, 230 MB), we won't me making them every time we run flagdata -- the automatic flag backup can be turned off by setting flagbackup=False. However, it's good to keep a record of the names of the backup files and the associated processing step, in case you wish to restore a previous version of the flags.
