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
