+##
+## Calculate the 'cooling function' profile with respect to the
+## given 'temperature profile' and the average abundance, redshift,
+## and column density nH, using the XSPEC model 'wabs*apec'.
+##
+## NOTE:
+## The output cooling function values should be the 'flux' values
+## with unit 'photon/s/cm^2' (different to 'calc_coolfunc_bands.sh').
+## These results will be used by 'fit_{beta,dbeta}_sbp' to derive the
+## (3D) gas density profile from (2D) surface brightness profile,
+## whose values have unit 'photon/cm^2/pixel/s'.

+##   * Rename from 'coolfunc_calc.sh' to 'calc_coolfunc.sh'
+##   * Clean up that do not calculate and output <coolfunc_bolo>
+## 2017-02-16, Weitian LI
+##   * Do not calculate and output 'flux_cnt_ratio.txt'
