Doppler Correction
For some spectral line setups, Doppler correction (position and velocity) should be applied. The benefit of Doppler Setting, since the VLA is dynamically scheduled, is that it calculates the sky frequency at the beginning of an SB and keeps this fixed for the duration of the SB. Doppler Setting can be specified for each individual baseband in the OPT, removing the burden to do this for each possible observing run by the observer. For more details, refer to the Doppler Correction section within the Spectral Line guide.
