| Description |
|
Please provide a mechanism for subtracting an externally-provided spectrum as part of the initial sky subtraction. This would take place before continuum extraction (and optionally replace it). The motivation is removing a bright lunar contribution to the sky. |

I think it's OK to use a single (i.e. non-spatially-varying) spectrum for this. We need to think about calibration, of course; for now we should probably accept a spectrum with the fibre response removed using fibre traces, and then apply the per-fibre correction. |
