This appendix gives details of any changes to the uplink software used to control the instrument. A list of changes is given in Table C.1 with a more complete explanation given below.
| Uplink | Revolution | SPR/SCREW | Comment |
| system | |||
| 21.3 | 36+ | SPR 1383 | band 3 bias reduced from setting 4 to 2. |
| 21.5 | 40+ | - | more accurate wavelengths in uplink tables. |
| 21.6 | 44+ | - | more accurate wavelengths in uplink tables. |
| 22.0 | 60+ | SCREW 116 | uplink time overhead reduced. |
| 22.3 | 64+ | SCREW 144 | exact match of up and down scans in SWS01. |
| SCREW 145 | more precise control of the run flags at the end of a down scan. | ||
| - | improved system sensitivities and noise parameters. | ||
| - | scan ranges in SWS01 adjusted. | ||
| - | less frequent photometric checks. | ||
| - | hi-level photometric checks no longer used. | ||
| - | 3E transition moved from 28 to 27.5. | ||
| 22.6 | 71+ | - | intervals between photo checks increased. |
| - | intervals between ref scans increased. | ||
| - | scan lengths in AOT1 50 instead of 40 steps. | ||
| 23.1 | 71+ | - | better FP gap calibration. |
| ?? | 78+ | - | band 3 bias reduced to setting 1. |
| 23.7 | 101+ | SCREW 169 | dark currents measured in activation. |
| 24.0 | 103+ | SCREW 162 | maximum reset of 4 seconds allowed for band 1. |
| SCREW 163 | longer darks in SWS01. | ||
| SCREW 164 | disabling of reference scans in AOTs 6 and 7. | ||
| SCREW 165 | wavelength-dependent FP gap width. | ||
| SCREW 166 | FP scan repetition rate minimally 3. | ||
| SCREW 167 | avoid breaking up short FP-scans. | ||
| 25.1 | 150+ | SPR 1689 | more accurate FP control table. |
| SPR 1691 | more ref scans for band 3. | ||
| 28.0 | 191+ | SCREW 188 | grating tracking also for short FP scans. |
| SCREW 189 | further suppression of unnecessary ref scans in SWS07 | ||
| SCREW 190 | make sure that all scans are followed by | ||
| proper dark measurements. | |||
| SCREW 191 | delay photo checks as much as possible within the AOTs. | ||
| SPR 1548 | improved FP velocity correction. | ||
| SPR 1787 | band 1 edge moved from 4.05 to 4.08  m. |
||
| 29.0 | 161, 237+ | SCREW 187 | acknowledge misalignment of bands 6 and 4. |
| 30.0 | 336+ | SCREW 232 | replace very slow scans in AOTs 6 and 7 by |
| repeated faster scans. | |||
| 33.2 | 584, 590+ | SPR 2307 | ref scans in AOTs 6 and 7 finally disabled. |
