| #354 | fixed | Hawk 2010 spectral calibration shifted | mggr | mggr |
| Description |
On examination, the Hawk spectral calibration appears to have shifted between 2009 and 2010. However, when processing using the new, shifted calibration, we see absorption features misplaced by the same amount as the shift. This implies the spectral calibration is incorrect. |

| #106 | invalid | Hawk data very noisy in some bands | benj | benj |
| Description |
Some Hawk bands are noisy to the point of uselessness. For example band 71 (1403nm), raw data from Nigg Bay line 3 (attached)
Also see over-water spectrum produced in level 3 image:
Spectrum cannot really be used for anything much - there is no means of quality controlling the data Data issue occurs over more than one flight, possibly there are sensor problems with some Hawk bands. See eg. Latera band 71, similar to Nigg Bay:
