 ===== Hobart 12m model =====
+==== Temporary HMI model ====
+This is a temporary model applied in HMI during broadband tests with the Callisto system.
+Original model:
+<code>
+P1 -0.0335
+P2 -0.4380
+P3 0.0066
+P4 -0.0026
+P5 -0.0023
+P6 0
+P7 0.1538
+P8 0.0214
+P9 0.0026
+</code>
+Additional offsets are
+<code>
+Az = +2.7 arcmin = 0.045 deg
+El = -4.0 arcmin = -0.0667 deg
+</code>
+The DC terms in the pointing model are P2 (Az) and P7 (El), so new model is:
+<code>
+P1 -0.0335
+P2 -0.393
+P3 0.0066
+P4 -0.0026
+P5 -0.0023
+P6 0
+P7 0.08713
+P8 0.0214
+P9 0.0026
+</code>

+This solution was put into HMI on 22 June 2016, ~23:45 UT (day 174). Parameters are:
+<code>
+G1 -0.0105
+G2 -0.0070
+G3  0.0180
+G4  0.0094
+G5 -0.0024
+G7  0.2059
+G8  0.0158
+G9  0.0007
+</code>
+Note that these were initially put in to HMI on June 20 but the sign for G4 was wrong. Not sure if that had a significant impact or not.
+Also updated HMI (on day 175, 00 UT) with revised station coordinates. Only sig change was to elevation which was 50m too low.
+<code>
+Lat, Long, Elevation:
+Before: -29.0465, 115.3467, 200.0
+After: -29.0469, 115.3465, 250.48
