Tutorials for the Caltech CASA Radio Analysis Workshop:

Calibrate and image a galaxy field for this mid-frequency EVLA observation. This includes:

  • Excising RFI from the data
  • Basic flagging and calibration steps
  • Imaging from one spectral window to full dataset
  • Using multi-scale, multi-frequency synthesis
  • Image analysis

Calibrate and make image cubes of the line emission from this asymptotic giant branch star. This is a high-frequency EVLA dataset. Includes:

  • Inspecting data; basic flagging & calibration
  • Subtracting continuum emission
  • Imaging the spectral lines
  • Imaging the continuum
  • Image analysis
  • Self-calibration

This low-frequency EVLA tutorial for the observation of a supernova remnant focuses on RFI excision as well as imaging wide-field and wide-fractional-bandwidth data. This includes:

  • Basic flagging and evaluation
  • Different methods for automatic RFI excision
  • Calibrating the data
  • Exploring different imaging options: widefield, multi-scale, and multi-frequency synthesis

Covers many aspects of ALMA data reduction as it details the reduction and imaging of line emission from a classical T Tauri star.

  • ALMA a priori calibration
  • Data inspection and flagging
  • Calibration
  • Continuum imaging & self-calibration
  • Applying continuum self-calibration to line data
  • Spectral line imaging
  • Extensive image analysis

Reduction, imaging, and analysis of the luminous infrared galaxy NGC 3256, including:

  • ALMA a priori calibration
  • Data inspection and flagging
  • Calibration
  • Imaging calibration sources
  • Imaging galactic continuum & self-calibration
  • Imaging line emission
  • Image analysis

Presents the basics of writing a CASA task, and provides examples of tasks that will be helpful and instructive.
