Description of LECP Data Quality Words

 

BITS* VARIABLE DESCRIPTION
0-7 NBI Number of Basic Intervals-contains the number of basic accumulation intervals over which the corresponding rate is accumulated. The accumulation time in milliseconds is given by NBI*BAI. (See Tape Header Variables, formerly Table B2.)
8-10 MPB Motor Position-contains the motor position at the end of the accumulation interval. MPB ranges from 0 to 7, corresponding to the LECP sectors 1 thru 8 respectively. If MP or NMS (see Tape Header Variables, formerly Table B2) are less than zero then MPB is invalid.
11 MCF Motor Centered Flag-is set if the status word indicates that the motor was centered within the sector. It is zero otherwise.
12 MMF Motor Movement Flag-is set if a motor step occurred during the accumulation interval. It is zero otherwise.
13 DL Discriminator Level-is set if the LECP Beta detector is set to its high threshold state. It is reset otherwise.
14-15 SS Switch State-defines which of the b or b' and δ or δ' rates are accumulated.

 

00=not known; 01= β ' - δ detectors on; 10= b - δ ' detectors on; 11=mixed
