IMP-8 Data Base Generator Program
User's Guide
1. GENERAL DESCRIPTION
The IMP-8 Data Base Generator creates Counts and PHA files for the cosmic
ray experiement (experiment number 52) on board the IMP-8 spacecraft.
Encyclopedia files, Count files, PHA files, a parameter card, and a file
catalog are the input to the program. Counts files, PHA files and an
updated file catalog are the output.
If PHA files are being generated, a pha data summary is printed every 45
albums. This summary consists of the time and s/c clock at the start of
the last album, the number of pha readouts padded (PAD), the number of MED
events with D or E amplitude of zero (DE=0), the number of MED -F events
with F amplitude greated than zero (NF>0), the number of MED F events
with amplitude of zero (F=0), the number of LED events with an A amplitude
of zero (A=0), the number of LED events with DS bits L1 and R equal (L1=R),
and the average number of counts per readout for the following rates :
A1.-B.-C (LED1), (A&B)1.-B.-C (LED2),
A1.B.-C (LED3), (A&B)1.B.-C (LED4),
D1.E1.F.G (MED1), D1.E1.-F.-G (MED2),
D1.E1.F.-G (MED3), and (D&E)2.E1.-F.-G (MED4)
If Counts files are being generated, a VIET PHA event summary is printed
showing the number of readouts padded and the number of readouts vs event
type. Also, a listing is printed of all LED sectored rate readouts that
are negative after correction followed by a summary of the correction
results.
At the end of each run a trend check summary is printed of the number of
readouts processed, accepted, undetermined, and rejected verse rate index.
The rate name for each rate index is given in the following table:

Processing is done on a 4-day interval basis, with interval 1 beginning on
Sept. 23, 1972 at 0000 hours (same as IMP-H). Since IMP-J was launched on
Oct. 25, 1973; the first interval containing data is 101.
The parameter card specifies which interval number is to be processed.
Processing may also be done on a time basis, however time periods may not
span Encyclopedia tapes. Processing ends when stop time is found or when
the end of the input encyclopedia file is encountered, whichever occurs
first.
