Record Format for FAT

This file is composed of 2800 byte records, sequential in time, with cadence equal to the stepping period of the LECP instrument. Each record consists has the following layout:

Bytes 1-200	Bytes 201-600	Bytes 601-800	Bytes 701-900	Bytes 901-2400	Bytes 2401-2800
KHED(100)	R(100)	IUNCS(100)	NSAMP(100)	IFILL(700)	ISTP(100,2)
Integer*2	Real*4	Integer*2	Integer*2	Integer*2	Integer*2

In the FORTRAN programs of the VGER processing, the FAT record can be represented by the following labeled COMMON block and Type Declarations for the variables:

COMMON/FOUT/KHED,R,IUNCS,NSAMP,IFILL,ISTP
INTEGER*2 KHED(100)	!OUTPUT RECORD HEADER
INTEGER*2 IUNCS(100)	!OUTPUT RECORD UNCS (64*PERCENT)
INTEGER*2 NSAMP(100)	!OUTPUT REC. #OF BASIC ACCUM. INTERVAL
INTEGER*2 IFILL(700)	!SPACE IN COMMON BLOCK FOR THE FLUXES
INTEGER*2 ISTP(100,2)	!STARTING AND ENDING MOTOR POSITIONS
REAL*4 R(100)	!OUTPUT RECORD COUNT RATES.(C/SEC.)

A list of contents of KHED(100) follows:

The array IFILL(700) reserves space for items calculated from the RATES(100) array using empirically derived expressions and coefficients that are loaded into labelled common blocks are the beginning of execution from the subroutine NEWBEG.FOR. In FORTRAN programs these items may be conveniently organized using the arrays IGAM(50), ICOMPR(30), IANGER(20), IUGAM(50), IUCOMP(50), IUANGR(20), IGFLX(100, ICFACT(100), FLUXES(100), IUFLUX(100) and ISTP(100,2). Note that ISTP(100,2) is prepared in the subroutine MTRCHECK_2001 and carries the information necessary to establish which a given channel might have directionally mixed data due to insufficiently rapid sampling compared to motor stepping.
