Gumball: MOS Database

Here is the reference database spectra for MOS. After selecting your instrumental configuration below, several spectra previously obtained for this configuration by the CFHT staff will be displayed. The first spectrum is usually an "optimal" calibration frame, that is, all the lamps are used to cover the whole spectral range. The other spectra are the individual lamps available in Gumball (when relevant) and a cut of a spectrum taken with the halogen lamp for flat-fielding calibration.

For each spectrum, the following information is provided:

Please, note that at this stage, the database is still incomplete. In the future, more data will be gathered and the database will offer additional information!
