Hmmm - first post in the forum ever. Not an encouraging sign but here goes anyway.
I am wanting to subtract sky frames from my object frames for my IFU data. I was going to do this by taking my sky frames and averaging the sky spectra over each frame, for all of the frames that I have. Then I was going to subtract this from my object frames to get the sky subtracted datacubes.
My question is - is the Starlink Datacube package capable of doing this? I've been reading the documentation, and it does seem to have the functionality for averaging groupings of spectra and plotting the results, but it doesn't seem to say anything about whether one can average the spectra and then go on to use the results to add/combine/subtract from other datacubes. Is it possible? Is there any other program out there that would be better for this function?
