Hello Eric,
Thanks for your quick reply.

Yes, I suppose the VLA analysts wrote out the archive data to a FITS
file. I can tell it's a FITS file by looking at it in ascii. Then I
read it into AIPS format with FITLD.

I am following the cookbook in section 4.2 and Appendix B. It does not
mention the verb IMHEADER. Am I looking at the wrong sections?

Okay. Thanks for stepping me through this.
The output from imheader is:
