simCluster in GAIA filters

[sivdur]

I use simCluster to create synthetic clusters with the $Gaia$ magnitudes using the following lines in the .yaml file but I only get the $u, g, r, i, z, J, H,$ and $K$ data.

    main_sequence:
        msRgbModel:     5     # 0 = Girardi, 1 = Chaboyer-Dotter w/He sampling,
                              # 2 = Yale-Yonsei (unsupported, 3 = Old (jc2mass) DSED,
                              # 4 = New DSED, 5 = PARSEC, 6 = New Yale-Yonsei (2018)

    white_dwarfs:
        wdModel:        4     # 0 = Wood, 1 = Montgomery (original), 2 = Althaus, 3 = Renedo, 4 = Montgomery (2018)
        M_wd_up:        8.0   # The maximum mass for a WD-producing star
        ifmr:           2     # 0 = Weidemann, 1 = Williams, 2 = Salaris lin,
                              # 3 = Salaris pw lin, 4+ = tunable

I think simCluster has no support for the $Gaia$ filters. Do you plan on simCluster and scatterCluster producing synthetic clusters in the $Gaia$ photometry?

all the best,
Sivan.

simCluster supports whatever filters are in your stellar evolution model. I suspect that you have an older version of the PARSEC model file. Check to see what filters are in that file, and if there are only this small handful, then update that model file from our GitHub models directory. I wouldn't suggest using scatterCluster any longer and we probably should make it no longer available. You can scatter your own photometry with whatever uncertainty you think appropriate.

Thanks for the quick replay but I double checked the PARSEC model file and it is the newest version containing the Gaia magnitudes. I also use Base-9 version 9.5.0 but when I type simCluster --version, I get Base-HEAD-HASH-NOTFOUND.

this is the output of simCluster --help

9.3.0 flags
===========
	--threads

		Turns off integration over secondary mass

9.4.4 flags
===========
	--noWDs
		Keeps simCluster from generating WDs

9.5.0 flags
===========
	--backend <int>
		Specify the desired back end:
			0 = File
			1 = SQLite

	--run <runID>
		Specify a previous run ID in the DB on which to base this run.
		Currently only supported by sampleWDMass and sampleMass.
		Only makes sense if you're using the SQLite backend.

	--priorParallax
	--sigmaParallax
	--startingParallax
		Specifies distance values in parallax. Can not be combined
		with any DistMod flag. Must all be specified simultaneously.

the header of the model file as follows:

# PARSEC Model
# Gaia DR2 SDSS ugriz 2MASS
%f G G_BP G_RP u g r i z J H K
%s [Fe/H]=-2.0000 [Alpha/Fe]=0.0000 l/Hp=1.7400 Y=0.248838
%a logAge=7.419956
# EEP Mass G G_BP G_RP u g r i z J H K

My BASE-9 code doesn't give the right version number either. Some benign error that has crept in.

As for the PARSEC file, that'll take an extra step or two. I see that the one on Github is very old, but Github won't let me upload the latest because of file size issues. Send me an email directly to ted.vonhippel@erau.edu and I'll send you a dropbox link to an updated PARSEC isochrone file that I've built.
