Cannot Find Spectrum Error

[chavezoscar009]

I am using BEAGLE v0.29.2 and am running into an issue where the program cannot seem to find the spectrum when I am trying to do spectro-photometric fitting.

I used the following command to call BEAGLE:

docker run --rm -it -v /Users/oac466/Desktop/BEAGLE-general:/BEAGLE_virtual_workdir --env-file Docker_env.list --user $(id -u):$(id -g) beagletool/beagle:0.29.2 --parameter-file /BEAGLE_virtual_workdir/params/Jorges_Fit.param --fit

And got the following output errors.

---> fitted: mass
 ---> fitted: nebular_logu
 ---> fitted: nebular_z
 ---> fitted: tauv_eff
 ---> fitted: tau
 ---> fitted: metallicity
 ---> fitted: specific_sfr
 ---> fitted: current_sfr_timescale
 ---> fitted: formation_redshift
 n_fitted:            9

I am having trouble figuring out why it does not find it as I am giving it the file path of the spectra in the .param file as shown below:

# ******************* PHOTOMETRY *****************************
#****************************************************************

FILTERS THROUGHPUTS = $BEAGLE_FILTERS/Jorge_Filters_Throughput.fits

FILTERS CONFIGURATION = $BEAGLE_FILTERS/Jorges_Filters.dat

PHOTOMETRIC CATALOGUE = $BEAGLE_DATA/Jorge_Photom_BEAGLE.fits

#****************************************************************
# ******************* SPECTROSCOPY *****************************
#****************************************************************

LIST OF SPECTRA = $BEAGLE_DATA/spectra/spectra_Jorge.list

# Example: FITS table
SPECTRUM FILE DESCRIPTION =   wl:colName:wav wl:conversion:1.E+10 flux:colName:flux  fluxerr:colName:fluxerr

Where the file spectra_Jorge.list has the following entry:

$BEAGLE_DATA/spectra/Jorge_Galaxy_Spectrum_1395.fits

Which points to the spectrum I want to do the spectro-photometric fitting. Any insights would be greatly appreciated.

hello @chavezoscar009, the issue is likely related to the naming of your spectra, section 4.1 of Beagle's manual:

NB: note that when combining spectroscopic and photometric data, the matching between photometry and spectrum, for the same object, is performed by means of the object ID defined in the photometric catalogue. In particular, for an object with photometric ID , the file name of the corresponding spectrum must start with the string , followed by the separator _. As an example, if the photometric catalogue contains the ID 123456, the file containing the list of spectra (passed by means of the keyword LIST OF SPECTRA in the parameter file) can contain a line /123456_spectrum.fits.

Okay cool, that seems to have fixed the issues here, glad it was a little naming convention and nothing more serious. So then I take it for the example script to work as well I would need to change the spectra name from example_spec_0.fits to 0_example_spec.fits.
