S2 transports and console:

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

LBACOR:

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

COR_DISP:

• Lag spectrum for each correlator product is ok (free from obvious birdies etc)

TVD:

• Phases, amplitudes and delays for all baselines/correlator products ok

Schedule file in COR$SCHED

• 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
• Check that correct STOP, FILE CLOSE, and NEWTAPES commands are commented and/or uncommented as appropriate.

Miscellaneous:

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