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 d or d' rates are accumulated. |
00=not known; 01=b' - d detectors on; 10=b - d ' detectors on; 11=mixed
Bit 0 is the Least Significant Bit. If all bits=0 then datum is missing.
