Hi,I'm trying to flag the bottom and upper channels of my data using uvflg, before running the vlba pipeline vlbarun to calibrate the data.  What I tried was using splat to apply the flags before running the pipeline, but the calibration didn't seem to go well.  These are the splat parameters I used:default 'splat'getn 2docalib 1flagver 0doband 1douvcomp -1outname '/Users/peter/AIP/test_with_rolloff.fitsoutclass 'splat1'go splatThe result was the amplitude and bandpass calibration after the pipeline was completely wrong.  Is there a better way to go about doing this, or what am I doing wrong?Best,Peter
