Overview
Data Description
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
