Gemini IRAF 1.13 available in recent Ureka 1.5.1 release

Version 1.13 of the Gemini IRAF package is now available in the latest version of Ureka, 1.5.1, released last month (http://ssb.stsci.edu/ureka). Linux users who need to reduce NIFS data (or use the task gemcube) are advised that the Red Hat Enterprise 6 build has sometimes been observed to produce non-optimally-aligned spatial grids when creating data cubes with gemcube/nifcube, a limitation that you can avoid by retrieving the Red Hat Enterprise 5 build (see "Installing Ureka Manually" in the documentation), whether or not you have a newer OS. The advantage of the RHE 6 build is that it also includes the Numba optimizing Python compiler.
