[McIDAS #PHG-988246]: Problem w/BLIZZARD IR imagery



Hi Brendon,

re:

This is the correct set of times for the BLIZZARD/G7-IR-4K datastet.

Hmm.  The second image is not correct.

Apparently, the image in question _was_ modified at 07:12 MDT
on September 23.  I am not sure how this could happen as
McIDAS invocations should not have write access to datasets
hosted on remote ADDE servers.  If they do, it is a bug
that needs to be found and squashed.

I restored an original copy of the image in question, and now the
IMGLIST information is what it should be:

% imglist.k BLIZZARD/G7-IR-4K.ALL 
Image file directory listing for:BLIZZARD/G7-IR-4K
 Pos Satellite/         Date       Time      Center   Band(s)
     sensor                                 Lat  Lon
 --- -------------  ------------  --------  ---- ---- ------------
   1  GOES-7 IR     13 MAR 93072  17:01:00    26   87 8
   2  GOES-7 IR     13 MAR 93072  17:31:00    26   87 8
   3  GOES-7 IR     13 MAR 93072  18:01:00    26   87 8
imglist.k: done

re:
> Thanks,

No worries.

Question:

- did you happen to run an IMGCOPY command that specified the
  BLIZZARD/G7-IR-4K.2 dataset element as the output?

  If not you, did someone in your course use it?

  I just want a starting point for my investigations...

Sorry for the problem!

Cheers,

Tom
