Missing keyword in fit_photometry_example.param

[marinatrevisan]

BEAGLE complains about a missing keyword when running fit_photometry_example.param with Docker Toolbox (version 1.6.2), Beagle 0.3.5 on a machine with Ubuntu 14.04:

I added a line with N_OBJECTS = 3 in the fit_photometry_example.param file and Beagle appears to run, returning the following message:

However, no output file is created in the results/ directory....

P.S: I don't know if it is relevant, but I am not using nebular emission (i.e., the keywords TEMPLATES NEBULAR, EMISSION LINES CONFIGURATION, and the parameters nebular_logU, nebular_xi, and nebular_Z are not used). In addition, I am using the SSP models available at http://www.bruzual.org/bc03/Updated_version_2016/BC03_miles_kroupa.tgz.

Hi Marina - are you trying to run with beagle_mode = 3 by any chance? This is a keyword required if you are making a mock catalogue, but shouldn't be required when fitting photometry which would be to run beagle with beagle_mode = 1

Hi Emma, yes, I was running with beagle_mode = 3 (by the way, I couldn't find the description of the beagle_mode anywhere in the manual)... If I run with beagle_mode = 1, Beagle does not run and I get the following error:

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Since the problem is not the keyword, I'm closing this issue and opening another one. :-)
