Examples

Create an accum table with 10-sec sampling, filling it with the calibration in 'first_cal' with the desired interpolation.

accum(vis='mydata.ms', tablein='', accumtime=10, incrtable='first_cal', caltable='accum1_cal')

If you plot 'accum1_cal' with plotms, you can see how the incrtable was interpolated.

Continue accumulating calibrations in 'accum1_cal' from 'second_cal'

accum(vis='mydata.ms', tablein='accum1_cal', incrtable='second_cal', caltable='accum1_cal')
