Day 1: CASA Basics and Calibration
On Day 1 we introduce CASA syntax and the CASA approach to data processing. We give an overview of the Measurement Set, and discuss the steps needed to calibrate ALMA data, including bandpass, phase, and amplitude calibration. We also describe the tools needed for data inspection.

Day 2 : Self-Calibration and Imaging; ALMA Archive and Science Data
On Day 2 we introduce the science data products provided by ALMA, and then focus on producing sky images from calibrated ALMA u-v data. Topics will include imaging, cleaning, self-calibration, and using the CASA viewer and other image tasks.
