LAN Pulse Height Archive Block Updates

1 July 1985

Item #3. Duty Cycle

This array changed from FA8(8) to FA8(8,14) which yields the fraction of time each channel was active for each sector.

Item #6. 1024 repetitions of the digitized events

IEVENT word 1 byte 4 has been updated to include an indication of which channels the event came from; i.e., whether it was (C1,D1) or (C2,D2). This information is encoded into the byte by either a 1 or a 2 multiplied by 16 and added to the byte. The sector number can be obtained as before by 'anding' with 15.

The new block definition is as follows:

HEADER 1020 BYTES
WART(8,14) 448 BYTES
T8(8) 32 BYTES
FA8(8,14) 448 BYTES
NEVENT 4 BYTES
NZERO 4 BYTES
IEVENT 8192 BYTES
10148 BYTES
