Note that all data flagged by cal table solution failures should be flagged earlier; otherwise, these data corrupt data that is not flagged. | |
Create rogues gallery of weird or unusual problems so we can confirm these problems have been resolved. | |
Look for online flags that may match bad data that should have been flagged at the beginning or end of scan. In some cases, these online flags had incorrect time stamps (start and end time inverted, start time too early). |

Pipeline DV07 gain solutions have low amplitude. |
Pre-bandpass phase vs. time on bandpass calibrator. The first integration was flagged by the manual reducer but not by the pipeline. |
Pipeline gain calibration amplitude on phase calibrator is low for DV24. |
Category: correlator problem The SPW 0 problem is visible in the bandpass calibration solutions. It is also visible in the gain calibration solutions contained in the AMC output. The SPW 3 problem has been reported on line 2.18 of . |
current AMC version | current AMC version | The 3 antennas that have large pointing solution offsets also have low gain calibration solution amplitudes. DVO1 is flagged in the pipeline gain cal. table. However, DV23 and DV24 are not flagged. |
First integration amplitudes are lower when DV15 is included. Without DV15, the outliers for all integrationsdisappear. plotms(vis=vis, xaxis='time', yaxis='amp', ydatacolumn='corrected', spw='9,11,13,15', scan='28', avgchannel='1e6', avgantenna=True, avgspw=True, coloraxis='antenna1', plotrange=[0,0,.38,.52], plotfile='uid___A002_X49a70a_X4d8_wDV15.png') plotms(vis=vis, xaxis='time', yaxis='amp', ydatacolumn='corrected', spw='9,11,13,15', antenna='!DV15', scan='28', avgchannel='1e6', avgantenna=True, avgspw=True, coloraxis='antenna1', plotrange=[0,0,.38,.52], plotfile='uid___A002_X49a70a_X4d8_woDV15.png') |
4 integrations here have low amplitudes. All low amplitudes come from DA42. None of these integrations show up in the online flags. |
The low amplitude points here come from many antennas. This integration is not flagged in the online flags file. plotms( vis='uid___A002_X609bf6_Xafe.ms', xaxis = 'time', yaxis = 'amp', ydatacolumn = 'corrected', field = '3', spw = '19', antenna = '!DA52', scan = '22', avgchannel = '1e6', plotrange = [0,0,2.3,3], coloraxis = 'antenna1' ) |
