EVLA Tutorials

  • Carbon Star IRC+10216: high frequency (36GHz), spectral line data reduction

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

  • Supernova Remnant 3C391: 6cm Polarimetry and Continuum Imaging, Mosaicking

Calibrate EVLA full polarization data, image a mosaic of the region in full Stokes and create a spectral index map. Includes:

  • Inspecting data; basic flagging
  • Calibration
  • Image Analysis and Manipulation
  • Polarization Imaging
  • Spectral Index imaging
  • Self-calibration

EVLA Tutorials for more Advanced Users

  • Supernova 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

  • Supernova 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
