Dear Eric Greisen,
</div>
<div>
<br /></div>
<div>
My primary purpose is to use the task 'pbcor' to make amplitude calibration to the image of an object, which is about 3.4 arcmin away
</div>
<div>
from the phase-tracking center. At X band, the resulting flux density is supposed to be affected significantly because the
</div>
<div>
HPBW is about 5 arcmin for a 25m antenna. If the relevant parameters for vlba have comparable values to that for vla, or I
</div>
<div>
could obtain the relevant parameters, I can use the task to do primary beam correction to get the reasonable
</div>
<div>
flux density level of the object under study. I'd be grateful if you could provide the relevant information. Thank you very much!
</div>
<div>
<br /></div>

Best regards,
