NGC3256 is the most amazing galaxy ever [...blah blah blah, To be written by Eric]

How to use this Casa Guide

This CASA Guide consists of two parts:

NGC3256 Band 3 - Calibration

NGC3256 Band 3 - Imaging

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.

Retrieving the 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.

[What else are we going to do to the data we provide?]

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.

You can download the data here:
