[Issues] Preastrom fails

[Jan Snigula]

Hi all,

preastrom reproducibly fails during the ingest of WFI science images.  
The error message:

[ocam-h02] 14:00:59 -

[ocam-h02] 14:00:59 -    Preastrometric Pairing Program Version: 2.0

in /usr/local/opt/astrowise/USNO-A2/-2147483648-2147483648.pmm


suggests, that the generation of the .pmm filename somehow goes  
wrong? This happens on the CDF test data as well as on newly observed  
WFI data.

Cheers,

Jan
