Data Set Summary
================
Data Set ID: ULY-J-EPAC-4-SUMM-OMNI-ELE-FLUX-1HR-V1.0
Instrument: EPAC
Instrument P.I.: Erhard Keppler
Data Supplier: Erhard Keppler
Data sampling rate: 1 hour
Data Set Start time: 1992-01-25T00:00:00.000Z
Data Set Stop time: 1992-02-28T23:00:00.000Z

Naming convention
-----------------
Data files in this data set are named according to the convention: 

Tyyddd.TAB

where   yy = the last two digits of the year ('92' for 1992)
       ddd = the day of the year covered by the file

Record format
-------------
These files can be read according to the FORTRAN format statement:
  '(a24,11(1x,1pe12.5))'
where 'a24' is the time stamp in PDS format: yyyy-mm-ddThh:mm:ss.sssZ.
The individual elements of the time field can be read according to the 
statement:
  '(i4,4(1x,i2),1x,f6.3,1x)' year, month, day, hour, minute, seconds.
thus a record may be alternatively be read according to the format:
  '(i4,4(1x,i2),1x,f6.3,1x,11(1x,1pe12.5))'

EPAC RECORD FORMAT (REFERENCE: [KEPPLERETAL1992A] page 322, table 4)

UDS REPRESENTATIVE: M. BRUNS (NSP::LINMPI::LINAX1::BRUNS)

NOTES: 

UDS data files
==============

These are ASCII files. The data entries in the files are always single
precision float values containing one hour averages in

  Flux / (s cm**2 sr)

starting at midnight for each day. The corresponding times are integers
indicating start of average. The entries are separated by blanks.
Then the total length of the ASCII records are: 168 Bytes with 24
records per file. Bad or absent data are flagged with -9.99999e+10.
The data entries are:

  Electrons Low (100-380 keV) Spin Averages Telescope 1-4 (ELTL1-4)
  Electrons High (E > 180 keV) Spin Averages Telescope 1-4 (EHTL1-4)
  Event-Rate Low, Medium and High Omnidirectional Channels (ERL,ERM,ERH)

The record structure is as follows:

1 character string (24 Bytes) with the format

             yyyy-mm-ddThh:mm:ss.sssZ
               yyyy = year
               mm   = month
               dd   = day
               hh   = hours
               mm   = minutes
               ss.sss   = seconds

11 reals (13 Bytes, e.g. -1.23456E+03) for

             ELTL1
             EHTL1
             ELTL2
             EHTL2
             ELTL3
             EHTL3
             ELTL4
             EHTL4
