 =====Criteria=====
-The basic health of a feed is determined by the phase rms as measured on the A and C correlators during a weekly "array health" correlator observation. Another indicator is the cryotemp.

 =====Antenna Feeds=====
+The 16 new feeds are on antennas: **1c,1e,1g,1h,1k,2a,2b,2e,2h,2j,2m,3c,3d,3l,4j,5b**
+The 6 antennas with no feeds (or missing other parts - not yet 100% clear) are: **1j,3f,3g,3h,4f,4h**
+The 19 antennas with rev 1 feeds *and* cryo readings are: **1a,1b,1d,1f,2c,2d,2f,2k,2l,3e,3j,4e,4g,4k,4l,5c,5e,5g,5h**
+The 1 rev 1 antenna with *unreachable* cryo is: 2

+=====bestantpols.py=====
+There is a great script that uses the results of the latest correlator array health obs and allows you to sort the antenna pols from best to worse.
+The available frequencies are 1430, 3040, 4500, 6667, 8400, 10000
