RtFCNotesRtFCOverviewThe RtFC depends on 4 distributed programs to transfer data from LBADR or Mark5 recording systems to a central location, and then invoke the DiFX software correlator. The software is written in Perl, with a couple of support programs used to extract a short time interval of data from the recorded data. Currently the system works interactively, support could be added to schedule automatic fringe checks. For normal LBA sessions, the fringe tester is run from a VNC session on pam0:1 (pkpam if at Parkes). The four programs are:
obs.pl runs an external programs (vsipack) to extract the requested time fragment from the (large) data files and optionally "compress" the data (select a sub selection of the data channels) before transferring. On Mark5 systems it uses the external programs m5time and m5slice which must be installed separately. To run the programs, they need to know the remote host running the other programs. This can be set on the command line, or preset via environment variables. In the RtFC directory there is a script " To run the system first start control.pl, then corr.pl. After this run A grab command from |
