  19 +; INPUTS:
  20 +; table_name : fits file name containing the grid
  21 +; filters : name of dustemwrap filters to be included in the GRID

  25 +; None
  26 +; OPTIONAL OUTPUT PARAMETERS:
  27 +; table_params= parameter names in the grid table
  28 +; table_pmins= parameter min values in the grid table
  29 +; table_pmaxs= parameter max values in the grid table
  30 +; table_pnvals= parameter number of values in the grid table
  31 +; table_plogs= 1=parameter values in log in the grid table, 0=linear
