cph, vcph, bcph, bvcph: Cooling + heating model for cool core clusters
This cph (Cooling+Heating) model is a modification of coolflow to include heating as described in Zhoolideh Haghighi, Afshordi & Khoshroshahi (2018). The peak temperature parameter is the peak of the emission measure distribution and occurs where the cooling and heating timescales are equal.
The coolflow model had parameters for low and high temperature but these are not necessary for the cph model since the emission measure does not diverge at low temperatures. The model integrates the emission measure distribution from 0.01 to 50 keV.
Velocity broadening can only be used with switch=2 or switch=3. See the cie model for further information and options.
For cph the parameters are:
| par1 | peakT: peak temperature (keV) |
| par2 | Abund: abundance relative to Solar |
| par3 | Redshift |
| par4 | switch (0 = calculate, 1 = interpolate, 2 = use AtomDB data, 3 = use SPEX data) |
| norm | Mass accretion rate (solar mass/yr) |
For the version with variable abundances (vcph) the parameters are:
| par1 | peakT: peak temperature (keV) |
| par2 | He: He abundance relative to Solar |
| par3 | C: C abundance relative to Solar |
| par4 | N: N abundance relative to Solar |
| par5 | O: O abundance relative to Solar |
| par6 | Ne: Ne abundance relative to Solar |
| par7 | Na: Na abundance relative to Solar |
| par8 | Mg: Mg abundance relative to Solar |
| par9 | Al: Al abundance relative to Solar |
| par10 | Si: Si abundance relative to Solar |
| par11 | S: S abundance relative to Solar |
| par12 | Ar: Ar abundance relative to Solar |
| par13 | Ca: Ca abundance relative to Solar |
| par14 | Fe: Fe abundance relative to Solar |
| par15 | Ni: Ni abundance relative to Solar |
| par16 | Redshift |
| par17 | switch (0 = calculate, 1 = interpolate, 2 = use AtomDB data, 3 = use SPEX dat) |
| norm | Mass accretion rate (solar mass/yr) |
For the version with velocity broadening parameter (bcph) the parameters are:
| par1 | peakT: peak temperature (keV) |
| par2 | Abund: abundance relative to Solar |
| par3 | Redshift |
| par4 | Gaussian sigma for velocity broadening (km/s) (switch=2 or 3 only) |
| par5 | switch (0 = calculate, 1 = interpolate, 2 = use AtomDB data, 3 = use SPEX dat) |
| norm | Mass accretion rate (solar mass/yr) |
