### Process step-guide: {{{
(1) $ chandra_repro indir=. outdir=repro verbose=2
(2) $ cd repro; mkdir -p evt bkg img spc/profile mass;
(3) $ cd evt; ln -s ../acis*evt2.fits .;
(4) $ ciao_procevt.sh
(5) $ cd ../bkg; ln -s ../evt/evt2*_clean.fits .;
(6) $ ciao_blanksky.sh
(7) ds9 open 'evt2*_clean.fits'; select edge region as the
*local background*, save as 'lbkg.reg';
and estimate the phonton counts:
(8) $ dmlist "evt2_clean.fits[sky=region(lbkg.reg)][energy=400:8000]" blocks
(9) $ ciao_bkg_spectra.sh reg="lbkg.reg" basedir=.. nh=<nh> z=<z>

(11) xspec> @xspec_lbkg_model.xcm

(12) cd ../img; ln -s ../evt/evt2*_clean.fits .;
(13) ds9 open 'evt2*_clean.fits', select the center of cluster,
save the region as 'center.reg'
(14) $ ciao_genregs.sh reg_in=center.reg bkgd=<bkgd>
(15) $ cd ../spc/profile;
$ ln -s ../../evt/evt2*_clean.fits .;
$ ln -s ../../bkg/bkgcorr_blanksky_lbkg.pi .; (maybe 'lbkg.pi')
$ ln -s ../../img/rspec.reg img_rspec.reg;
(16) ds9 open 'evt2*_clean.fits' with regs 'img_rspec.reg';
adjust the regions and save as 'rspec.reg'
(17) create conf file '<NAME>_spec.conf' like:
basedir ../..
reg rspec.reg
bkgd bkgcorr_blanksky_lbkg.pi | lbkg.pi
nh <nh>
z <redshift>
(18) $ ciao_deproj_spectra.sh reg="rspec.reg" bkgd=<bkgd> basedir="../.." nh=<nh> z=<z>
(19) $ xspec
xspec> @xspec_deproj.xcm
xspec> fit
xspec> @~/astro/scripts/xspec_coolfunc_v2.tcl
(input 1)
xspec> exit
(20) fix 'NULL' values in 'tcl_temp_profile.qdp' & 'tcl_temp_profile.txt'
(21) $ xspec
xspec> newpar <..>=<..> (bind all kT's and Abundanc's)
xspec> fit (get avarage Temp and Abund)
xspec> exit
(22) $ cd ../../img;
create '<NAME>_expcorr.conf' with contents:
basedir ..
reg sbprofile.reg
nh <nh>

(32) $ fitnfw <z> [rmin_kpc]
(33) $ qdp nfw_fit_result.qdp # check fitted nfw profile, and ajust 'rmin_kpc'
(34) add 'nfw_rmin_kpc' to 'global.cfg'
(35) $ fitmass global.cfg c # calculate the center values

(37) $ chandra_collect_data_v3.sh

(42) update the data of 'T(0.1-0.5 R500)', 'Z(0.1-0.5 R500)' ...
## --------------------------------------------------------
(43) $ cd ../..; # in 'repro' dir
$ cp -a mass lxfx; cd lxfx;

$ getlxfx . 500 200 # for all results (with errors)
## --------------------------------------------------------
(46) $ cd ..; cd spc/profile;
calculate cooling time and Csb value:
$ ciao_calc_ct_csb.sh
check the region whether exceeds ccd edge, and answer y/n
check results in file 'ct_csb_results.txt'
---
Alternatively:
$ ciao_calc_ct.sh
$ ciao_calc_csb.sh
check the region whether exceeds ccd edge, and answer y/n
check results in file 'cooling_results.txt' and 'csb_results.txt'
