-===== Comments:\\ ===== 
-\\ 
-**FIRST HOUR IS FOR FRINGE-CHECKS**\\ 
-\\ 
-First 1 hr of this experiment (0000 - 0100 UT) is a bright source (0537-441) for real-time fringe-checks. ​ Please try and be onsource for some of this first hour in order to verify fringes.\\ 
-\\ 
-Create a separate directory for these fringe-checks and record the first hour of data into this directory.\\ 
-\\ 
-After the first hour, a new directory should be started for recording, called v190c. ​ Record data after 01:00 UT into this directory.\\ 
-\\ 
-After 01:00 UT, the fringe-check directory can be deleted. ​ **PLEASE BE CAREFUL NOT TO DELETE ANY OF THE DATA FROM AFTER 01:00 UT**\\ 
-\\ 
-Note that all fringe-check data at ATNF telescopes should be recorded to the xraid disks, due to the high data rates at ATCA, Parkes, Mopra. ​ Hobart should record to their xraid and Tid should record to their removables.\\ 
-\\ 
-Note also that this is not how we usually run fringe-checks. ​ Usually we have a separate schedule. ​ For v190c, as an out of session observation,​ the fringe-check is included in the schedule with the targets.\\ 
-\\ 
-**DISKS - ATNF TELESCOPES**\\ 
-\\ 
-Record on /data/xraid at ATCA, Parkes, Mopra (two xraid sets). ​ Both sets should be mounted on the one PC recorder machine before the observations get underway. ​ One set should be recorded to for the first 11.5 hrs (~2.7 TB) and the second set should be recorded to for the second 11.5 hrs (another ~2.7 TB).  This should almost completely fill the two sets.  Note that each disk set is split into two partitions or volumes and that changes of directory are required when switching to a new volume.\\ 
-\\ 
-The durations and changeover times for the partitions/​disk sets will therefore be:\\ 
-\\ 
-Record on /​data/​xraid* at ATCA, Parkes, Mopra (two xraid sets)\\ 
-\\ 
-|1st xraid set, 1st partition: 01:00 - 6:45 UT|\\ 
-|1st xraid set, 2nd partition: 06:45 - 12:30 UT|\\ 
-|2nd xraid set, 1st partition: 12:30 - 18:15 UT|\\ 
-|2nd xraid set, 2nd partition: 18:15 - 24:00 UT|\\ 
-\\ 
-**DISKS - HOBART**\\ 
-\\ 
-The durations and changeover times for the two partitions are:\\ 
-\\ 
-Record on /​data/​xraid* at Hobart (one xraid set).\\ 
-\\ 
-|1st xraid set, 1st partition: 01:00 - 12:30 UT|\\ 
-|1st xraid set, 2nd partition: 12:30 - 24:00 UT|\\ 
-\\ 
-**DISKS - TIDBINBILLA**\\ 
-\\ 
-Record on /​data/​removable/​* at Tidbinbilla (2 x 4 x 400 GB sets).\\ 
-\\ 
-At Tid the removables should be changed mid way through the experiment, at 12:30 UT.  Approximately 1.4 TB of data will be on each set of removables.\\ 
-\\ 
-The durations and changeover times for the two sets of removables are:\\ 
-\\ 
-|1st removable set: 01:00 - 12:30|\\ 
-|2nd removable set: 12:30 - 24:00|\\ 
-\\ 
-**DISKS - GENERAL**\\ 
-\\ 
-All stations should record using disko as usual (ATCA, Parkes, Mopra should choose "Chans 1->​8"​).\\ 
-\\ 
-Please note here on the wiki (under "​Observing comments for each antenna"​) the label on the disk and the partition on the disk used for each time range for this experiment.\\ 
-\\ 
-**TIDBINBILLA AND HOBART FREQUENCIES AND POLARISATIONS**\\ 
-\\ 
-Tid only has LCP at 1.6 GHz and should set up to record 4 channels of LCP at 256 Mbps using the vsop profile on the DAS, matched to the 4 channel frequencies given in the table. ​ This will allow Tid to match LCP at all 4 frequencies for the ATNF antennas.\\ 
-\\ 
-Likewise, Hobart should also set up to record LCP at 256 Mbps using the vsop DAS profile. ​ Like Tid this will allow LCP coverage of all 4 frequencies of the ATNF antennas, and will exactly match Tidbinbilla. ​ This setup will require splitting the RF signal and setting up two IF chains, one into each IFP of the DAS. \\ 
-\\ 
-^ IFP#1 Skyfreq ​      | 1650.00 LCP |\\ 
-^ IFP#2 Skyfreq ​      | 1682.00 LCP |\\ 
-\\ 
-**DAS & Recorder Setup**\\ 
-\\ 
-Hobart and Tidbinbilla connect DAS directly to VSIC as per normal\\ 
-\\ 
-Parkes, ATCA & Mopra connect both DAS to single VSIC input using '​Huygens'​ cable. DAS#2 should be configured to be the higher frequency and connected to input#2 (input with clock lines connected).\\ 
-\\ 
-\\ 
-**SCHEDULES**\\ 
-\\ 
-ATCA schedule on leon as v190c\\ 
-\\ 
-Mopra schedule - I don't know how to create vlobs schedules on bigrock (SJT). ​ Chris will sort out the Mopra schedule.\\
