Release of 28 April 2000.

• Fixed test of second station in scan in UV plotting routine. Before fix, extra spurious points would be plotted when the first station and not the second was in the scan. 14Sep1999 RCW.

• When getting the polarization from pol and RCHAN and LCHAN are specified, use them to set IFCHAN. Before RCHAN and LCHAN were only used when IFCHAN=R or L. 15Sep1999.

• Protect against no scans scheduled. 27sep1999 RCW.

• Added catalog plotting capability Franco and RCW sep99.

• Some tweaks to the tape handling section of the manual. 19oct99.

• Check for duplicate channels came before all channel info was known in some cases. Moved SFINFO call to after setup parameters are derived. 25oct99 RCW.

• Issue warning if there are DOPPLER scans scans with SOURCE not the same as DOPSRC and both are line sources. This is probably not wanted. 2 Nov 1999. RCW.

• Change www.nrao.edu/... links to www.aoc.nrao.edu. 9dec99 RCW.

• Issue warnings about the output data rate through the FIR. The limit is 44236-2048 (41188) spectral channels per 0.131 second correlator tic (can be longer observing time with speedup). The correlator always transfers 2048 spectral channels divided by the spectral averaging, even if it is going to throw most of them away. This limit is higher than the output data rate limit for 2 or more baseband channels, but can be the limiting factor with 1 channel. Wish list: 13dec99 RCW. Warning added 19Jan2000 RCW.

• Improve warnings when synchronizing tape starts causes short tape stoppages. 26Jan2000 RCW.

• Fix handling of tabs by keyin under Linux. 27Jan2000 RCW.

• Modify warning when doppler or freq in schedule move frequency outside IF specified in freq.dat. 30Jan2000 RCW.

• Added subroutine (SCANID) to help warning and error messages identify the offending scan. A few such messages modified. Many more needed. 3 feb 2000. RCW.
• At the requist of Ralph Marson who is writing AIPS++ fillers, I have restricted CALCODE to be a letter (which is capitalized by SCHED) or a number. 10 Feb 2000 RCW.

• Added / at end of flag lines in flag file. 22 Mar 2000 RCW.

• Added USED and VLAVB to SETCOP - were missing. 24 Mar 2000 RCW.

• Added setup parameter NOISEFRQ to control Pie Town noise cal switching rate. It wants to use the VLA rate when the Pie Town link is being used. 4 April 2000 RCW.

• For 512 bit mode, don't complain when autoallocate is not used. 10 April 2000. RCW.

• Add a text capability to pass a cover letter from the schedule to the sch and summary files. 11Apr2000 RCW

• Set time for a readback test in 512 Mbps mode to 4 minutes. 12 April 2000. RCW.

• Beef up the description of CORWTFN in the manual and add a warning if 1:4 fan out is requested with the ZEROPAD option. 19 April 2000. RCW.

• Add various enhancements to the interactive RD plotting option. 19 April 2000. Franco.

• Added note for observations with large output data set sizes to consider requesting high density output tapes. 19 April 2000 RCW.

• Added machine readable correlator parameters to end of .sum file for observations to be correlated in Socorro. 19 April 2000 RCW.

• Added support for VLBA4 systems in Vex and in the setup defaulting routines. 24 Apr. 2000 RCW and Huib.

• Vex debugs, changes, and additions from Huib Apr 2000. Bug fixes or enhancements in the logic dealing with narrow filters, the JIVE checker and some rounding issues. Added the cover letter to the VEX file. Added digits to source coordinates.
