Photometry and Stellar Masses for GRB Host Galaxies with Eemission-line Spectra

We present broad-band photometry and SED fits to a sample of GRB host galaxies for which spectra were published by us previously (Kruehler et al., 2015, A&amp;A, 581, 125).<br><br>We collected relevant photometric data from the literature (see references), as well as our own photometry using a variety of telescopes and instruments. These auxiliary data were reduced in a consistent manner using methods described elsewhere (Kruehler et al., 2011, A&amp;A, 534, 108). The used fits files are provided with this data set, where each fits file is named according to the instrument, filter and GRB.<br><br>We then fit the data in a similar manner as described in detail in Schulze et al., 2017, arXiv:161205978 using a modified version of LePhare (Arnouts et al., 1999, MNRAS, 310, 540; Ilbert et al., 2006, A&amp;A, 457, 841) and stellar population synthesis models of Bruzual &amp; Charlot (2003, MNRAS, 344, 1000).<br><br>The resulting files provided with this data release are given in GRBhosts_SEDs.tar.gz, which contains for each GRB of interest:<br>- One pdf containing the plot with the photometry and the best fit model<br>- One ascii file with (ending .spec). This ascii file contains the photometric data (AB system, corrected for Galactic foreground reddening after Schlafly &amp; Finkbeiner 2011, ApJ, 737, 103), in a block of 27 lines with 7 columns. The columns correspond to the magnitude, magnitude error, mean wavelength (AA), width of the filter, the magnitude of the best-fit galaxy template. The last two columns can be ignored. After that, two columns follow with the best fit galaxy template.<br><br><br>The resulting physical parameters of the burst are given in the file GRBhosts_SEDparam.txt with the individual columns as described in the header of the file. The file header also contains more info on the filters used, as well as the fit parameters (cosmology, dust reddening, priors). <br><br><br><br><br><br>
