The observations of project BL175 were correlated with the new capability of the VLBA to observe multi-phase centers across the primary beam. Is the correction to the fluxes by the primary attenuation made during the correlation? or should it be done after imaging?

I have found in the literature that some authors made this correction in their images, and assuming that the VLBA antenna response is similar to the VLA antennas. I suppose that this means that in the task PBCOR I could simply set PBPARM(2) = 1. Then I could run the task on my maps of the multi-phase centers.  Is this approach correct?


Gisela.
