Updated 2013B PIT fixes guide star bug
A bug in PIT 2013.2.1 prevents the calculation of guide star availability for the given target, instrument configuration, and weather conditions. This does not prevent proposal submission but it is confusing and undesirable. This problem has been fixed with the release of PIT 2013.2.2 on March 26, 2013. The new PIT can be downloaded from here. The guide star likelihoods will be calculated automatically once a program is loaded into the new PIT.
The 2013A PIT that is still needed for Director's Time and Poor Weather proposals is not affected.
We apologize for the inconvenience.
