Subj:	DE PWI ingest on NDADS

I had looked into the DE PWI data set.  The data is on the optimem platters and
is approximately 12 gbs of total data. Before we ingest the data on NDADS
I have comme across few questions.

1) The PWI_YYDDD.DAT files where YY is the year and DDD is the day of the 
   data in the file.  Looking at those files, there size varies from anywhere
   between 10,000 to 34,000 blocks. The problem is of those big files and
   the retreival of those files once they have been ingested ?

2) Each optimem of PWI has LFC_AMP.CAL, LFC_BWD.CAL, MAG_AMP.CAL.
   Does that imply that these files which keep on occuring again and again
   belong to that particular set of files?  Does the output of those files is
   same on each optimem platter or is it different?

3) Similarly each optimem has:
    Test_DC.DAT, Test_LFCA_AMP.DAT....and so on. Are they the same on all 
   optimems or do they differ?

My concern is most on the big files and their retreival. Hope we can come up 
with some solution ????.
