SCHED: is the program used to schedule most VLBA projects and is being adopted by the EVN (European VLBI Network) the VSOP orbiting VLBI satellite project as the standard scheduling program for those systems. The SCHED tasks are available at I.R.A. on the alpha axp workstations and on the PC with Linux OS. Note that, to avoid conflicts with the tcsh shell, the original names sched, skedconv, schclean and uptime have been renamed as vsched, vskedconv, vschclean, vuptime. To work with SCHED tasks a personal username on Alpha or Linux WS is required. The SCHED environment is initialized by default at login time. However, if the tasks do not work in your personal account please verify that: 1) the environment variable SCHED is correctly defined (echo $SCHED): DEC ALpha: /soft/astro/sched PC Linux: /usr/local/sched 2) the directory /usr/local/bin is present in your path (echo $PATH) 3) the existence of both the SCHED directory and the tasks vschclean, vsched, vskedconv, vuptime in the /usr/local/bin directory. If one of this conditions is not verified, please contact Franco Tinarelli. SCHED is a program for scheduling Very Long Baseline Interferometer (VLBI) Observations. Currently, it can be used to schedule VLBA and Mark III observations on antennas that use the VLBA real time control software. Support for Mark IV observations on any station that can read VEX format schedule is being added. It can be used to schedule any Mark II observations. To work with sched use the command: vsched or: vsched < input.key SKEDCONV can convert the DRUDG file from PC-SCHED (or SKED) into a SCHED input file. To work with skedconv use the command: vskedconv SCHCLEAN is a shell script that delete the output files produced by sched task. To work with schclean use the command: vschclean <schedname> UPTIME computes rise and set times. To work with uptime use the command: vuptime The SCHED User's Manual is available in three different forms: HTML pages at the address: http://www.ira.inaf.it/ira-docs/calcolo.html Postscript files at the same web address Manuals in room 307 Contact Person: F.Tinarelli tinarelli@ira.inaf.it
