luminosity_function_of_lGRBs

This is the set of data files and codes used for the project Paul, D. 2018, MNRAS, 473, 3385 (https://ui.adsabs.harvard.edu/#abs/2018MNRAS.473.3385P). Please cite this paper if you are using any of these codes or databases.

The following is a brief description of the codes, as well as the databases used and created.

debduttaS_functions.py : A set of generic functions. specific_functions.py : A set of functions used for this work.

k_correction.py : Calculates the k-factor for both Swift and Fermi, for GRBs with known/fixed spectral parameters. k_table.txt : Tabulates the k-factor for fixed spectral parameters as a function of redshift.

Fermi--all_GRBs.txt : The Fermi data from the Fermi catalogue. Swift--all_GRBs.txt : The Swift data from the Swift catalogue. Swift--GRBs_with_redshifts : The Swift data for GRBs with known redshifts, from the Swift catalogue.

rho_star_dot.txt : The numerical values of the Cosmic Star formation rate, from Bouwens et al. (2015).

selecting_common_GRBs--all.py : Selects all the GRBs common to both Swift and Fermi. selecting_common_GRBs--wkr.py : SElects GRBs with measured redshift (by Swift), common to both Swift and Fermi. common_GRBs--all.txt : Output of "selecting_common_GRBs--all.py". common_GRBs--wkr.txt : Output of "selecting_common_GRBs--wkr.py".

establishing_the_correlation--step1--Tan_method--blind.py : Attempt parameter estimation as in Tan et al. (2013). establishing_the_correlation--step2--Tan_method--corrected.py : Correct the modification procedure and check. establishing_the_correlation--step3--looking_for_possible_systematics : Try to explain the discrepancy.

estimating_pseudo_redshifts_and_Luminosities--with_names.py : Segregate the classes of GRBs and estimate pseudo redshifts.
