ccurve_create.tcl is a TCL script (plus associated
csh scripts) that makes it is possible to
calculate cooling curves (plasma emissivities, in
units of erg cm^3 s^-1) as a function of plasma
temperature using the hot plasma codes available
in the XSPEC spectral fitting program.
Element-or-line-specific cooling functions can
also be created. These can be used in
hydrodynamical simulations to assess the total
cooling rate, calculate the luminosity in a
specific wavelength/energy range, or more
generally to calculate X-ray or UV line diagnostics.
