| + | Field system and HMI have been updated | ||
| + | |||
| + | ==== 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> | ||
| + | |||
| + | |||
| + | |||
| + | ==== Version 2016.151 ==== | ||
| + | 2 June 2016 | ||
| + | |||
| + | Observations over 24he. Little change to rms before and after | ||
| + | |||
| + | <code> | ||
| + | Data: | ||
| + | xEl mean -0.0013 | ||
| + | xEl RMS 0.007 | ||
| + | El mean -0.015 | ||
| + | El RMS 0.008 | ||
| + | |||
| + | After solution: | ||
| + | xEl RMS 0.007 | ||
| + | El RMS 0.009 | ||
| + | </code> | ||
| + | |||
| + | Solutions applied err2016.151 | ||

| {{:operations:yg_pointing_2016_151.png?200|}} | {{:operations:yg_pointing_2016_151.png?200|}} | ||
| + | |||
| + | 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 | ||
| + | </code> | ||
