Welcome to program SCHED. Version: 10.00 Release Sept. 15, 2011 The manual is at http://www.aoc.nrao.edu/software/sched/index.html Unix users should set $SCHED to the base area where SCHED is installed. Most run time messages will be in sched.runlog Some useful commands to give now if running interactively: SCHedule= : Specify input file. PLOT : Invokes uv, xy, rd, and uptime plotting. FREQLIST=lowF,highF : Make frequency list (MHz). Then exit. EXIT : Leave program. / : End of inputs - run program (or EXIT). SRREAD: Reading source catalog: Program_input RDSET: Reading setup file: globGbps.6cm STREAD: Reading station catalog: ./sta.sess311.dat STREAD: Reading locations file: /usr/local/sched/catalogs/locations.dat GETFREQ: Reading frequency file: /usr/local/sched/catalogs/freq.dat INPUT: Found 356 input scans.

Below are the closest matches with at least some overlap in RF frequency. You can use FREQLIST (a main program input) to get the frequency catalog group and IF numbers that are available. Or you can look in freq.dat in the catalogs area. Since SCHED cannot confirm the validity of your setup, check and be very sure it is correct! In the table below, a match is indicated by a T. A mismatch is indicated by F.

TWOHDSET: Using 16 Mbps per track record rate. Mark IV format on disk only. SCHOPT: First output scan will be number 1 WRTMSG: Special message from routine AUTODOWN: * Stations using automatic tape allocation or disk recording systems are being removed from scans when the source is below the antenna pointing limits. This behavior can be overridden using DODOWN. SCHOPT: There will be 356 output scans ( 1 - 356) from 298/08:35:00 to 298/23:00:00 CHKSCN: 280 scans had more than half the antennas arrive on-source after the start time. This could be normal if using duration scheduling with small gaps. SUMOPE: Writing summary file gb072.sum STALST: WARNING - A station has zero axis offset, which is unlikely. Accurate positions, including axis offsets are needed for correlation. Is your station location information adequate? See the summary file station list to see which stations are suspect. OMSOUT: Writing OMS file gb072.oms VXWRT : Writing V E X file gb072.vex EFLSBERG has 44 Tsys measurements. Maximum interval = 18 minutes. MEDICINA has 44 Tsys measurements. Maximum interval = 18 minutes. ONSALA85 has 47 Tsys measurements. Maximum interval = 18 minutes. TORUN has 44 Tsys measurements. Maximum interval = 18 minutes. WSTRBORK has 43 Tsys measurements. Maximum interval = 18 minutes. YEBES40M has 47 Tsys measurements. Maximum interval = 18 minutes. ARECIBO has 16 Tsys measurements. Maximum interval = 18 minutes. VXSCH: Tsys calibration at most MkIV stations is taken during every gap in recording, but these appear over 15 min apart for the stations listed above! This can be improved by inserting gaps at regular intervals. Note this is not an issue for Westerbork or Arecibo WRTMSG: Special message from routine VXSCH: For most MkIV stations (e.g. most of the EVN) the calibration diode is only fired during gaps in recording. Although the total power is monitored continuously during scans, the calibration diode must be fired regularly to allow these total power levels to be accurately converted to system temperatures. It is recommended that, where possible, you leave a gap in recording at least every 15 minutes to allow the system temperature measurements. The gap should be at least 15 seconds, but you should also try to ensure that these gaps are long enough that all the antennas are on source before the next scan starts. Note that warnings about Westerbork and Arecibo can be safely ignored because they have continuous system temperature measurements. ARECIBO : only 2 out of 16 Tsys measurements are on-source VXSCH: Stations listed above are affected by slewing during Tsys calibration WRTMSG: Special message from routine VXSCH: Note that although you may have left gaps during which the system temperature can be measured at MkIV stations, one or more stations are still slewing at the scan starts. System temperatures measured when the antennas are slewing are unlikely to be useful. The time between useful Tsys measurements is therefore likely to be longer than the recommended 15 minutes at the stations listed above. Note that warnings about Westerbork and Arecibo can be safely ignored.
