Version 8.1

We needed to get the GBT catalog corrections and the Vex file fix into the wild.

• Change the way the durations of scans in the Vex file are calculated to avoid having scans overlap by a second due to round off of the duration to even seconds. Feb. 4, 2009 RCW.

• Add VLA to VLA1 and VLA27 in freq.dat to support mixed mode observations. Feb. 20, 2009 RCW.

• Add a section to the summary file of correlator blocks to help the analysts make jobs. Feb. 4, 2009 RCW.

• Add calcode to the oms file. Jan. 26, 2009 RCW.

• Update some catalog information for the GBT. There were two GBT entries for a while which resulted in loss of the axis offset for the GBT. Also remove the freq_US.dat master file which is no longer used. Jan 23, 2009. RCW.

• Make an svn branch for version 8 support. Jan. 26, 2009 RCW.

• Fix spurious blank in time for exper_nominal_start and stop in the Vex output. Jan. 26, 2009

• Warn if the rate of creation of record files (blocks of data between record stoppages - can be several scans) is more than 1000/day. The actual limit is 1000 per disk module for Mark5A and Mark5B, but we don't know ahead of time how big the modules will be and what other observations will be on the module so we can't use that actual limit. The limit used is an average of one every 86 seconds so is unlikely to be reached unless someone is stopping recording every scan in a fast switching phase referencing observation, which would be unwise while there are still sync times at the correlator. All of this will go away with Mark5C and the software correlator. Jan. 21, 2009 RCW.

• No longer warn about short record stops when synchronizing starts as needed by the current use of Vex. Disks don't care Jan. 21, 2009 RCW.

• Change the number of sources that can be used for optimization runs from 100 to 1000 (CSUB and CELLS). Jan. 5 RCW
