Oddities

1. All CARMA data have auto-correlations preceding the cross-correlations. Some calibration programs, most notably selfcal and mfcal, cannot handle this? File bugzilla ? Use the select=-auto keyword to filter them out.

2. Some of the correlator setting has half edge channels and should always be flagged.

3. Most CARMA data have a noise source added, which can be used for bandpass calibration. However, be sure not to apply linelength or baseline corrections to these data. Use select=-source(noise) to filter them out.
