Subject: How to read VLA FITS file into matlab

Lorant,

My name is Ronny Levanda and I'm a Ph.D student at Bar Ilan university Israel.

I received a FITS file from the VLA and I need to load the (u,v,visibility) calibrated measurements into Matlab. The data should be u,v data of a single field.

I have found a lot of information regarding the general FITS format (i.e., how a general FITS file is built), but nothing regarding the specific fields that concern me (visibility, u,v). 

Using FITSread of Matlab I get the 4 binary tables, but I don't know how to extract the visibility information.

Can you please provide me the format of the VLA files I need?

Thank you,

Ronny
