| Help on exportuvfits task:
| |
| | |
| Convert a CASA visibility data set to a UVFITS file:
| |
| | |
| This task write a UVFITS file, a general format data set used
| |
| to transfer data between different software systems. It is
| |
| written in floating point format. Many spectral windows can
| |
| be exported to UVFITS only if they have the same shape. For
| |
| transferral to the AIPS interferometric packages, multi-source
| |
| and combinesp options should be set to true.
| |
| | |
| Keyword arguments:
| |
| vis -- Name of input visibility file
| |
| default: none; example: vis='ngc5921.ms'
| |
| fitsfile -- Name of output UV FITS file
| |
| default: none; example='3C273XC1.fits'
| |
| datacolumn -- Visibility file data column
| |
| default: => 'corrected'; example: datacolumn='model'
| |
| Options: 'data' (raw),'corrected','model','weight'
| |
| field -- Select field using field id(s) or field name(s).
| |
| [run listobs to obtain the list id's or names]
| |
| default: ''=all fields
| |
| If field string is a non-negative integer, it is assumed a field index
| |
| otherwise, it is assumed a field name
| |
| field='0~2'; field ids 0,1,2
| |
| field='0,4,5~7'; field ids 0,4,5,6,7
| |
| field='3C286,3C295'; field named 3C286 adn 3C295
| |
| field = '3,4C*'; field id 3, all names starting with 4C
| |
| spw -- Select spectral window/channels
| |
| type 'help par.selection' for more examples.
| |
| spw='0~2,4'; spectral windows 0,1,2,4 (all channels)
| |
| spw='<2'; spectral windows less than 2 (i.e. 0,1)
| |
| spw='0:5~61'; spw 0, channels 5 to 61, INCLUSIVE
| |
| spw='*:5~61'; all spw with channels 5 to 62
| |
| spw='0,10,3:3~45'; spw 0,10 all channels, spw 3, channels 3 to 45.
| |
| spw='0~2:2~6'; spw 0,1,2 with channels 2 through 6 in each.
| |
| spw='0:0~10;15~60'; spectral window 0 with channels 0-10,15-60
| |
| NOTE ';' to separate channel selections
| |
| spw='0:0~10^2,1:20~30^5'; spw 0, channels 0,2,4,6,8,10,
| |
| spw 1, channels 20,25,30
| |
| antenna -- Select data based on antenna/baseline
| |
| default: '' (all)
| |
| If antenna string is a non-negative integer, it is assumed
| |
| an antenna index
| |
| otherwise, it is assumed as an antenna name
| |
| antenna='5&6'; baseline between antenna index 5 and index 6.
| |
| antenna='VA05&VA06'; baseline between VLA antenna 5 and 6.
| |
| spw='0~2:2~6'; spw 0,1,2 with channels 2 through 6 in each.
| |
| spw='0:0~10;15~60'; spectral window 0 with channels 0-10,15-60
| |
| NOTE ';' to separate channel selections
| |
| spw='0:0~10^2,1:20~30^5'; spw 0, channels 0,2,4,6,8,10,
| |
| spw 1, channels 20,25,30
| |
| antenna -- Select data based on antenna/baseline
| |
| default: '' (all)
| |
| If antenna string is a non-negative integer, it is assumed
| |
| an antenna index
| |
| otherwise, it is assumed as an antenna name
| |
| antenna='5&6'; baseline between antenna index 5 and index 6.
| |
| antenna='VA05&VA06'; baseline between VLA antenna 5 and 6.
| |
| antenna='5&6;7&8'; baseline 5-6 and 7-8
| |
| antenna='5'; all baselines with antenna index 5
| |
| antenna='05'; all baselines with antenna name '05', vla antenna
| |
| antenna='5,6,10'; all baselines with antennas 5, 6 and 10
| |
| timerange -- Select data based on time range:
| |
| default = '' (all); examples,
| |
| timerange = 'YYYY/MM/DD/hh:mm:ss~YYYY/MM/DD/hh:mm:ss'
| |
| Note: if YYYY/MM/DD is missing dat defaults to first day in data set
| |
| timerange='09:14:0~09:54:0' picks 40 min on first day
| |
| timerange='25:00:00~27:30:00' picks 1 hr to 3 hr 30min on next day
| |
| timerange='09:44:00' data within one integration of time
| |
| timerange='>10:24:00' data after this time
| |
| nchan -- Number of channels to select (superceded by spw)
| |
| default: => -1 (all)
| |
| start -- Start channel (superceded by spw)
| |
| default => 0;
| |
| width -- Channel averaging width (value > 1 indicates averaging)
| |
| default =>1; example: width=3
| |
| output data will average channels in groups of three.
| |
| writesyscal -- Write GC and TY tables

| multisource -- Write in multi-source format
| |
| default: => True;

| |
| writestation -- Write station name instead of antenna name
| |
| default: True;
| |
| async -- Run asynchronously
| |
| default = true; highly recommended.
