Ticket
#232
Description

Specim calibrated the Eagle and Hawk sensors at the start of the 2009 season. We need to validate the calibration as best we can - this will primarily require an independent verification by FSF.

Mismatches in the overlap region between Eagle and Hawk still exist, as in previous years: Eagle/Hawk spectra using 2009 calibration over water

#250
Description

We need a program that will read in a dark frame file, rescale it to mimic that for a different integration time and then output the new file.

Basic level: Read in data file, multiply by a user-specified scaling factor (except pixels 1 & 2 on band 1 for each line), output new data file.

What we really want: Same, but calculate scaling factor from differential of integration times - check relative data values for existing dark files to try and work out if the result of changing the integration time is just a linear scaling (hopefully) or something more complicated, then implement appropriate algorithm. The user should also be able to specify a scaling factor as above if they prefer.

Gold-plated: Same, but also account for changes in framerate and in spectral/spatial binning. May be worth spending half an hour to check whether the effects of altering these are also just linear scaling, but if they're not then don't include them (assume constant).
