 At each observatory you need to run the ''​obs.pl''​ program. This connects to the correlator processors at Parkes and copies the requested data down the network. ''​Obs.pl''​ should be run remotely by who ever is running the fringe test, as they sometimes hang and have to be restarted. This should be run after the correlator processes are started. Once you have logged onto the recorder PCs, you need to cd to the directory where the data is being recorded then run obs.pl. If the recorder is currently been run via ''​cdisko''​ or other programs which use "​recorder_server",​ then an alias "''​recdir''"​ is setup which will automatically change to the correct directory. Usage will normally be something like: At each observatory you need to run the ''​obs.pl''​ program.

 +Katherine DBBC3 is not supported by Sched. You will need to manually create vexfile to match setup. Note there are usually multiple independent streams of data.  Usually it will be 2 streams, one for each pol. The bandwidth will probably not match other stations - e.g. probably 32 MHz channels. Also There is currently easy way to select which pol RtFC chooses.

 If you are recording to a remote recorder you need to ensure RTFC_ANTID (and RTFC_ANTNAME) are set. For remote recorders which generally only record data from a single teleacope this will normally be setup in the login scripts. cave-store can record data from Mopra and ATCA. Aliases have been setup "​mopra"​ and "​atca"​ to setup the environment. E.g.: If you are recording to a remote recorder you need to ensure RTFC_ANTID (and RTFC_ANTNAME) are set.

 Normally if the telescope IF spectrum is inverted, a flipped DAS profile should be used. However for 64 MHz recording the spectrum cannot be "​flipped"​.
