Overview
This CASA Guide describes the imaging of the supernova remnant G55.7+3.4.. The data were taken on August 23, 2010, in the first D-configuration for which the new wide-band capabilities of the WIDAR correlator were available. The 8-hour-long observation includes all available 1 GHz of bandwidth in L-band, from 1-2 GHz in frequency.
The data have also been flagged and calibrated, and the corrected data for G55.7+3.4 have been split off to
Preliminary data evaluation
plotms, plotants, viewer (?)
A priori calibration and flagging
Antenna position correction
Flagging non-operational antennas
Automatic RFI excision
Hanning-smoothing data
Using phase calibration source for preliminary bandpass calibration
Running testautoflag
Evaluating results & manual flagging
Flagging lowest edge of SPW 0 ...
