The ultra-rapid EOP measurements use either modified IVS schedules (with Hobart in “tag-along” mode) or bespoke schedules. In either case, the usual slogit procedures can be used but you should make sure that the correct skd file is in /vlbobs/ivs/sched/ on ops-serv2 before starting & make sure it doesn't get overwritten by downloading the unmodified schedule.
Prepare the scheduLe and procedure files as usual but make sure that checkmk5 will not attempt to generate autocorrelations, and that preob and postob procedures look like this:
define checkmk5 00000000000x "sy=/home/oper/bin/auto_cor_check_web_1bit_8MHz_hb.sh & "scan_check "mk5=get_stats? "mk5=status? enddef define preob 00000000000x onsource disk2file=abort,, !+5s scan_check mk5=get_stats? mk5=status? systemp12 mk5=dot? clkoff maserdelay enddef define postob 00000000000x scan_check !+3s sy=/home/oper/bin/data2vortex.sh & clkoff maserdelay enddef
Also check that /home/oper/bin/data2vortex.sh is going to do the right thing, check that the directory on vortex is mounted on mk5hb.
