Mr Jack Martin
My understanding of calibration is a neon lamp as I own a Lhires III.
Do you mean John is rewriting BASS calibration to include bias-dark-flat field corrections ?
By calibration frames do you mean bias-dark-flat frames ?
The ccd temp was set to -5 c as told by an experienced amateur consequently all spectra taken so far are at that temperature.
