How to use this Casa Guide
This CASA Guide consists of two parts:
To start the data reduction process from the raw data, begin with the Calibration section: NGC3256 Band3 - Calibration. Once you have completed that section, or if you would like to skip over the calibration process, proceed to NGC3256 Band3 - Imaging.
For both portions of the guide, we will provide you with the full CASA commands needed to carry out each step. Simply copy and paste the commands into your CASA terminal. For more help getting started with CASA, see Getting_Started_in_CASA.
Obtaining the Data
Raw Data
The data were taken in six different datasets over two consecutive nights: April 16-17, 2011. There are three datasets for April 16th and three for April 17th. Here we provide you with "starter" datasets, where we have taken the raw data in ALMA Science Data Model (ASDM) format and converted them to CASA Measurement Sets (MS). We did this using the importasdm task in CASA.
Along with the Measurement Sets, we also provide some tables that you will need for the calibration. These include the System Temperature (Tsys) tables, which contain corrections for atmospheric opacity, and Water Vapor Radiometer (WVR) tables, which contain the atmospheric phase corrections determined by the water vapor radiometers on each antenna.

Once the download has finished, unpack the file:
# In a terminal outside CASA
tar -xvf ngc3256band3raw.tgz
Calibrated Data
For those wishing to skip the calibration section, we also provide the fully-calibrated data on the science target.
