Abstract

Fits files used for the machine learning algorithm used in the article. These data are mostly derived from observations with the IRAM-30m telescope in the context of the ORION-B project, cf., https://www.iram.fr/~pety/ORION-B/ The original version of this archive is available at https://www.iram.fr/~pety/ORION-B/data/orionb-2020-gratier.tar.xz All the maps are gridded in a custom set of coordinates, with the origin set on the PDR of the Horsehead Nebula (RA-Dec coordinates provided in the header), and with an axis position angle rotated by 14 degrees with respect to the North-South orientation. The FITS file headers are WCS compliant, and our custom set of coordinates should be understood by any standard FITS reader. fits subdirectory contains the integrated line intensities maps (files ending in -area-cropped.fits) and the peak temperatures (files ending in -tpeak-cropped.fits) of the Orion B molecular cloud in 18 molecular tracers, used as features for the machine learning algorithms used in the paper. Maps of two physical parameters NH2 and Tdust derived from Hershel data and used as predictor are also included, you should refer to Lombardi et al. (2014A&A...566A..45L) for the details of the Herschel data reduction. The molecular line is encoded in the string at the begining of the filenames, see Table 1 for the corresponding frequencies. (3 data files).
