This is a subset of SEDs which can be used to calculate magnitudes of some relatively widely ranging and hopefully useful objects, in combination with rubin_sim.
The python package rubin_sim can be installed with conda from conda-forge or with pip by following the directions in this README.
This photometry_reference directory contains 5 subdirectories containing a sample of reference SEDs, chosen to represent a range of different types of SEDs suitable for addresing various calibration questions. These subdirectories are:
- galaxies (composite galaxy SEDs from Andy Connolly)
- photoZ_outliers (containing galaxy templates which are most likely to result in catastrophic failures in determining redshifts using photo-Z techniques. Templates provided by Sam Schmidt, via Tony Tyson).
- quasar (containing a single quasar SED which has been generated by combining a composite spectrum from 2204 QSO spectra from SDSS (vanden Berk et al) with a simple model for the flux behavior beyond the SDSS wavelengths, provided by Zeljko Ivezic).
- sn (containing SN SEDs at various points in their time evolution, these come from the SN templates created by Peter Nugent),
- stars (containing several stars from blue to red -- km10_7250.fits_g45 being the bluest and equivalent to about an F0 type main sequence star [7250 indicates its effective temperature .. hotter=bluer], down to the m3.0Full.dat SED which represents a red Mdwarf. The Kurucz models come from Kurucz 1993, while the Mdwarf is a composite empirical spectra from SDSS extended in wavelength by other observations.)
In each SED file, there may or may not be a header line starting with '#', but the data is always contained in columns of wavelength (in nm) and flux - 'Flambda' specified, that is, in units of ergs/cm^s/s/nm, although the flux is arbitrarily scaled (that is, the SEDs are not photometrically pre-scaled to any particular magnitude).
The directory 'mag_info' contains some brief explanations of magnitudes as
can be calculated by rubin_sim.photUtils.
