Version 8.0

Released on Dec. 13, 2008.

• Warnings issued if source motions are significant when writing Vex files. Vex output does not yet support motions. Dec. 13, 2008 RCW

• Increase digits in the Vex file specification of station positions, station velocities, and axis offsets. Dec. 12, 2008 RCW.

• Increase digits available for items in the summary table. This was driven by some large disk byte counts. Dec. 12, 2008 AP and RCW.

• Various catalog updates.

• Started adding an indicator of when the Tsys measurements are done at each station. This will eventually control whether to give warnings of inadequate gaps when TSCAL=GAP. Nov. 5, 2008 RCW

• Change the distribution tar files. A 1MB file used to be a problem so various schemes were used to keep the tar files small. That is no longer an issue, so the distribution tar file contains everything a user should need, including binaries for several architectures. Nov. 3, 2008 RCW.

• Change the scheme for building makefiles for different architectures. There is now one master makefile and some simple scripts that use sed to configure that makefile for each target. Nov. 1, 2008 RCW

• Add VLA freq.dat entries for Methanol at 6668 MHz and OH at 6030 and 6035 MHz. Oct. 29, 2008 RCW.

• Warn of scans longer than 40 minutes -- they can cause problems when there are mid-scan pack changes or other mid-scan difficulties. Oct. 25, 2008 RCW.

• Update sources.vlba and locations.dat to current correlator values that are based on solution 2008a_astro from GSFC. The VLA pad positions were note updated from the ones based on 2005f, but the changes would have been less than the likely errors. Oct. 8, 2008 RCW.

• Change SUMITEM defaults to ELA (average elevation) and DWELL Oct. 2, 2008 RCW.

• Add more of the input file names to the list in the summary file, including the satellite Spice files. Sept 20, 2008 RCW

• Add a line in the VLA Observe deck (xxxxobs.y) file giving the reference antenna - which is also the single dish antenna. New variable VLARFANT supports this. Most users should not worry about it. Sept. 20, 2008 RCW

• Fix error in elapsed time calculation that caused non-recording scans not to be included. Sept. 10, 2008 RCW

• Removed VLAxIF and VLAxROT file specifications. They are no longer used. The input variables are still read, but not passed to the obs.y file. Sept. 8, 2008 RCW

• A wish list item was to allow mixing of VS and VA/VX mode observing, for example to do DELZN sections in VS mode. We believe that this is simply a matter of specifying the right mode. Complications will arise at the correlator when the delay needs to change. Email was exchanged about this around May 16-20, 2008. RCW Sept. 10, 2008.

• Make OPSKIP function during pointing observations. It was blocked for such observations. Sept. 11, 2008 RCW.

• Add VLA integration time (//DS line). Also remove VLAROT and VLAIF names from //LO card. Sept. 8, 2008 RCW.

• Add HSA examples Aug. 14, 2008. RCW.

• Add note about 2cm frequencies being different in standard setups and when BAND='2cm' Aug. 13, 2008

• Switch to gfortran on MacOSX 10.5. Aug. 11, 2008 RCW.

• Add warning suggested by Yuri Kovalev is the default RA or Dec were used, generally indicating a typo in the catalog. May 1, 2008 RCW

• Remove requirement for autotape for disk. RCW

• Remove the Arecibo, GBT, and N140 entries for the S2 recording system from the stations catalog. Add GBT_COLD. Mar. 4, 2008. RCW.

• Much work on the manual, mainly reducing influence of tape. Late Feb. 2008. RCW

• Convert the summary of tape change times into a summary of time ranges for recording and total bytes. Feb. 29, 2008. RCW

• Warn if using both satellites and planets that it might cause a crash. Feb. 15, 2008 RCW.

• Allow the 2-bit, 8-channel, 32-MHz sample rate MarkIV mode in okmodes.f. Jan. 24, 2008

• Much updating of the manual. Dec. 13-?, 2007 RCW

• Remove obsolete examples egiii.key, egmk5vex.key egmk5vlba.key Dec. 13, 2007 RCW.

• Add parameter EVLA to allow the VLA to reach frequencies allowed by the EVLA but not the VLA. Sept. 26, 2007. RCW.

• Convert all stations to Mark5 in the station catalog. Nov. 8, 2006 RCW

• Found and fixed a bug in the calculation of station parallax for satellite positions. March 26, 2007. RCW.

• Put indicator of continuous recording in .sch file. May 8, 2007.

• Increase maximum number of setups. June 8, 2007 RCW.

• Add setup parameter M4PATCH and subroutine chk4geo.f to support geodetic type setups. This is incomplete, but is at least making a polarization study of the geodetic stations (VLBA providing both polarizations) possible. June 2007 RCW.

• Add 24GHz band. Aug 28, 2007

• Put SCHED under revision control with SVN. Adapted Cormac Reynolds version that had about a 2 year history. Aug 31, 2007. RCW.
