agnSED/
The agnSED/ folder contains the SED for our AGN model.
cepheid_lc/
The cepheid_lc/ folder contains models for the variability of Cepheid variables. These files show the change in magnitude in each of LSST's six filters (the second through seventh columns of the file) as a function of phase (the first column of the file). These files are used by the method applyCepheid in Variability.py in sims_photUtils
eb_lc/
The eb_lc/ folder contains models for the variability of eclipsing binary stars. See the discussion of cepheid_lc/ above. These files are used by the method applyEb in Variability.py in sims_photUtils
flatSED/
The flatSED/ folder contains an SED for which the flux as a function of frequency is linear.
galaxySED/
The galaxySED folder contains models for galaxy bulges and disks. SEDs in the galaxySED folder come from the Bruzual & Charlot models with the Chabrier (2003) IMF and are calculated based upon 4 different star formation histories:
...
With each of these star formation histories the ages of the galaxies come in 40 different age steps between 1.585 Myr and 12.5 Gyr. Furthermore at each age they are available at 6 different metallicities which use the Padova 1994 isochrones from Z=0.0001 - 0.05 where solar Z is set at Z = 0.02.
mflare/
The mflare/ folder contains files that encode the variability of flaring M dwarf stars. In this case, unlike the files in cepheid_lc/ and eb_lc/ above, the first column is an absolute time axis in days (rather than in the phase of some period). The second through seventh columns are still changes in magnitude for each of LSST six filters. These files are used by the method applyMflare in Variability.py in sims_photUtils
microlens/bh_binary_source/
The microlens/bh_binary_source/ folder contains files like lc_14_25_75_8000_0_.6_32 which are light curves for magnification due to microlensing by black holes. The first column of the file is the time in years. The second column is the multiplicative factor by which flux is increased. The third, fourth, and fifth columns are not used. These files are used by the method applyBHMicrolens in Variability.py in sims_photUtils.
rrly_lc/
The rrly_lc/ folder contains two sub-folder: RRab/ and RRc/. These each contain light curves for the variability of RR Lyrae stars. As with cepheid_lc/, these files contain data specifying how much the star's magnitude increases or decreases in each of LSST's six filters as a function of periodic phase. These files are used by the method applyRRly in Variability.py in sims_photUtils
ssmSED/
The ssmSED/ folder contains SED models for solar system objects.
starSED/
The starSED/ folder contains SED models for stars. These SEDs are further divided into sub-directories as follows
gizis_SED/
The .dat versions are the originals from John Gizis in Mar 2011. K. Krughoff modified these on Mar 28 2011 as follows:
...
The interpolated spectra are in *_interp.dat
kurucz/
The kurucz/ sub-folder contains models from the Kurucz 1993 stellar atmospheres atlas. The files have names like:
...
- The letter and number after the 'k' denote the logarithmic metallicity relative to solar. km30 means that log(Z/Z_solar) = -3.0. kp25 means that log(Z/Z_solar) = +2.5
- The next number is the effective temperature of the lower Kurucz model used to interpolate the effective temperature (we desired models that sampled T on a finer grid than provided by Kurucz). In the model above, the effective temperature is 5270 K, and it was interpolated from a model at 5250K and a model at 5500K.
- The number after the g denotes the log of the surface gravity (g00 means log(g) = 0, g15 means log(g)=1.5)
- The final number is the effective temperature of the model
mlt/
The mlt/ sub-folder contains SED models for MLT dwarfs.
wDs/
The wDs/ sub-folder contains SED models for white dwarfs. These models come from Bergeron. The files have names like:
