calculate_extinction_values(filters, atmec, galec, verbose=False)[source]

Calculate the extinction values for a set of filters

Parameters:

  • filters (str) – The file containing the lephare compiled filter list

  • atmec (str) – Extinction law to use, to be searched in $LEPHAREDIR/ext if relative
