The MFSA block is based on the completion of one full MFSA schedule cycle. There are 8
schedules in a cycle, and one schedule is performed during each LAN logical record cycle
based on 4 formats. Hence, the completion of all 8 MFSA schedules requires 32 formats
(1024,2048,4096,8192 seconds, respectively, at the 1024,512,256,128 bps rates). The
M'(120) and F'(60) detectors are sectored by 8 and the M(30) and F(150) detectors are
sectored by 4 over the 10, 20, 40, or 80 spins per LAN logical record (4 formats). In
order to normalize the pulse height spectra, the rate channels for each detector are
included. Two count rate averages are computed for each channel: one over the entire MFSA
cycle and another over just the time corresponding to the accumulation of the pulse height
spectrum of the detector in question. This is to aid in establishing whether the MFSA data
can be used as characteristic of the entire interval.

Spectra Accumulation Times |
| |
| Units: |
Accumulation times in seconds |
| Type: |
R*4 |
| Length |
32 words, 128 bytes |
| Arrays: |
TMP(8) - Time for each of the eight sectors of the one repetition
of the M' spectrum.
TFP(8,2) - Time for each of the eight sectors of the two repetitions of the F' spectrum.
TM(4) - Time for each of the four sectors of the one repetition of the M spectrum.
TF(4) - Time for each of the four sectors of the one repetition of the F spectrum. |
| Note 1: The LAN data system stops the
accumulation of a spectrum if any of the channels overflows. Hence, the accumulation time
can be less than nominal if the count rates are high. The presence of overflow is signaled
in the status trailer byte 18. |
