Airmass missing

Hi,

I noticed that the airmass is missing from my Extended Format AAVSO Report, although the "Single Image Photometry" page gives the value correctly. Strangely the "Available Images" list just gives 0.000.

My question is that a way to get airmass to show up in my report.

Maybe I need to give more

Maybe I need to give more information:

I take images with MaxIm DL ver 6.03. I plate solve them with the included Pinpoint LE.

My fits header has:

DATE-OBS

SITE-LONG and SITE-LAT

CRVAL1 and CRVAL2

These values would appear to be sufficient to calculate the airmass. Note that my Lat & Long is also in the VPhot's Telescope  Setup.

The fits header does not give AIRMASS or OBJALT.

What is really puzzling is that VPhot does indeed calculate the airmass correctly as an intermediate result, but not in the final AAVSO report.
