Release of 02 July 2002.

• Die if no location given for a station. 18 Oct 2001 RCW.

• Fixed use of un-initialized variable in Vex stuff that caused problems occasionally on systems that do not automatically initialize variables. This was detected by a user doing plots. 18 Oct 2001 RCW with fix found by Franco and agreed to by Huib.

• Improve error message when OBSTYPE indicates recording will be done, but all scans are flagged NORECORD. 13 Dec 2001 RCW

• Default IATUTC to value from SLA_DAT. 27 Dec 2001 RCW

• Change TSETTLE to 6 for VLBA stations after experience with a 43 GHz phase referencing run that had 15 second scans. 28 Dec 2001 RCW

• When there are between 2 and 24 sources and a UV plot is requested, make a separate panel for each source. 2 Jan 2002 RCW

• Add OBSTYPE = CONFIG to trigger a UV plotting and optimizing mode useful for configuration studies. A map of the station locations is plotted and stations can be clicked on and off (and highlighted) for plotting. An optimizing mode is built in that tries combinations of available stations and rates them based on the number of cells filled in a uv grid. Related parameters include MAPLIM, GRIDNR, GRIDNT, GRIDMIN, GRIDMAX, and GRIDW0. Also added the configuration studies section of this manual. Jan-Apr 2002 RCW.

• Write extlo and extlosideband parameters to VLBA control files for non-VLBA antennas whenever that IF channel was not used in the previous scan in addition to whenever the value actually changes. This was needed by Effelsberg. 14 Jan 2002. RCW.

• Alter 3mm examples to no longer claim that the peaking setup needs to be similar to the observing setup to avoid formatter reconfigure. This is not true if FORMAT=NONE. 14 Jan 2002. RCW.

• Checked the Lat/Long/Ht to XYZ conversion. Altered the ellipsoid by 1 meter to conform to current values found on the web. The conversion now agrees with examples at geodetic sites at the cm level assuming that everything is in WGS84, which is closely tied to the ITRF. 29 Jan 2002 RCW.

• Check that each frequency set is within the IF's specified in the frequency catalog. This gives a check after application of Doppler or schedule specified frequencies. 4 Feb 2002 RCW.

• Improve the ability to change the maximum number of stations and some other parameters with only one change in sched.inc. As a result, the sched.inc file must be invoked before schset.inc. 2002may01 RCW.

• Some restrictions on processing 512 Mbps observations at JIVE have been lifted. 2002may Huib

• There have been a number of updates to the catalogs for the EVN stations, both in capabilities and positions. Cormac Reynolds 2002may

• The ``settling time'' (TSETTLE) for the VLBA antennas was increased from 2 seconds to reflect better what is actually seen in phase referencing observations. This will lengthen the gap between scans when using dwell time scheduling. 2001apr RCW.

• Change the default for RECORDER, DAR, and CONTROL to blank, which gets interpreted as NONE. Should have no effect in practice because the catalogs have always specified these. But with the advent of DISK for Mark5, this will change.

• Add MINSETUP to the station catalog to deal with cases where there is a minimum scan change time regardless of the slew and settling times, but where this minimum time should not be added to scan changes with long slews.
