LBA Correlator Checklist (``Pocket Guide'')

S2 transports and console:

$\bullet$ Day number and time on S2 recorders is correct (against master clock)
$\bullet$ S2 mode is correct
$\bullet$ Individual tapes are in correct order in each group.
$\bullet$ The first S2 playback contains the tapes for the first station in the schedule file, and so on for each station in the schedule.
$\bullet$ Tape playback times differs from real time by a multiple of 10 seconds

LBACOR:

$\bullet$ Correct schedule loaded (using S2FILE)
$\bullet$ Correct correlator CONFIGuration has been PROGrammed
$\bullet$ Correct integration time and blank pulses set with CYCLE
$\bullet$ For pulsar gating, phase offset (PSRPH) set correctly
$\bullet$ Output data file opened or closed as required (using FO and FC)
$\bullet$ On each "GO", check that the playback time difference in a multiple of 10 seconds

COR_DISP:

$\bullet$ Lag spectrum for each correlator product is ok (free from obvious birdies etc)

TVD:

$\bullet$ Phases, amplitudes and delays for all baselines/correlator products ok

Schedule file in COR$SCHED

$\bullet$ check these settings:
EXPERIMENT $<$expt-name$>$
DATE $<$year$>$ $<$day number$>$
FREQ/BW $<$freq$>$ $<$bandwidth$>$ [$<$freq$>$ $<$bandwidth$>$]
SOURCE_LIST $<$expt-name$>$
ANTENNAS $<$number antennas$>$ plus individual antenna information
CONFIG $<$correlator configuration$>$*
BASELINES $<$number baselines$>$* plus individual baseline information
* If CONFIG used and $<$correlator configuration$>$.BSL exists in COR$SCHED, BASELINES is not necessary
$\bullet$ Check that correct STOP, FILE CLOSE, and NEWTAPES commands are commented and/or uncommented as appropriate.

Miscellaneous:

$\bullet$ Source list $<$expt-name$>$.TAB exists in COR$DB and has correct positions
$\bullet$ For pulsar gating, $<$source$>$_$<$expt-name$>$.$<$station$>$ exists in COR$PULSAR
