Individual Lessons

Getting Oriented in CASA

We'll begin by getting you oriented in CASA.

• Your first task and script
• Orienting yourself with a new data set

Calibrating Data

Next we'll look at how we calibrate data.

• The three columns and basic calibration flow
• Basic phase and amplitude calibration
• Applying calibrations
• Flux calibration using a quasar
• Flux calibration using a solar system body
• Bandpass calibration

Flagging Data

A large part of the human input to data reduction comes from identifying problematic data, which is usally removed from the data set in a process called "flagging."

• Basic flagging
• Basic data inspection

Manipulating Data

• Splitting and averaging data
• Manipulating the three columns
• Combining several data sets

Imaging

• Demonstrating the effect of calibration - your first imaging example
• Basic continuum imaging
• Basic line imaging
• UV continuum subtraction

Self-Calibration

• Basic self-calibration
• Averaging in self-calibration
• Self-calibration tips and tricks

Analysis

• Derive image statistics
• Make moment maps
• Fit a gaussian
• Inspection using the CASA viewer
