Caltech CASA Tutorials

Tutorials for the Caltech CASA Radio Analysis Workshop:

• EVLA: SN2010FZ -- Wide-band, narrow-field imaging; C-band (5-7 GHz)

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

• EVLA: IRC+10216 -- Spectral line, Ka-band (36 GHz)

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

• EVLA: G55.7+3.4 -- Wide-band, wide-field imaging; L-band (1-2 GHz)

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
