[Philippe Heraudeau]

Hello,

GAstromTask complains that some source list do not have DATE_OBS:

The reduced frame has DATE_OBS but SourceList does not 'see' it for this 
frame as shown here:
a = ReducedScienceFrame.filename == 
'Sci-PHERAUDEAU-WFC-------197-A5506-4-Red---Sci-53878.4378739.fits'
awe> print a[0].DATE_OBS
2006-02-20 02:13:24.00
awe> print a[0].raw.DATE_OBS
2006-02-20 02:13:24.00
====================================================================
a = SourceList.name == 
'GAS-Sci-PHERAUDEAU-WFC-------197-A5506-4-Red---Sci-53878.4378739.fits.slist'
print a[0].frame.filename,a[0].frame.DATE_OBS
Sci-PHERAUDEAU-WFC-------197-A5506-4-Red---Sci-53878.4378739.fits
Traceback (most recent call last):
   File "<stdin>", line 1, in ?

Thanks for having a look at it.

Philippe
