# Cooling Rate Tables for NEMO v1.0 implemented in PION v3.0

This directory contains the cooling rate tables for all ions in NEMO v1.0, calculated using CHIANTIPy version 15.0 (Del Zanna et al. 2021; Young et al. 2003). These tables follow the naming convention of CHIANTIPy, where ion names like `C_1` refer to neutral carbon, and `fe_21` corresponds to Fe20+ ion.

The cooling rates account for key radiative processes—bremsstrahlung, line radiation, and two-photon emission—over an extensive range of temperatures (10 K to 10^9 K) and electron densities (1.0 to 10^6 cm^−3), ensuring applicability across various astrophysical environments.

Each cooling rate table is structured on a 2D grid with:
- x-axis: Logarithmic Temperature (`logT_Table`) values ranging from 1 to 9 in increments of 0.1.
- y-axis: Logarithmic Electron Number Density (`logne_Table`) values from 0 to 6 in increments of 0.5.
