There are two main python file, CI_P04_expression_test.py and CO_CI_fit.py.
CI_P04_expression_test.py is used to draw CI population using expression from (Papadopoulos 2004). run by $ python CI_P04_expression_test.py The plots are style of (Papadopoulos 2021) Figure 5 Using coefficient from (Papadopoulos 2004), the results are the same as (Papadopoulos 2021) Figure 5 In the following analysis, we choose coefficient from LAMDA website. We also plot iso-density curves for Tcmb=8.62K (Spiderweb) for comparison. In the following analysis, we choose Tcmb(z)=(1+z) Tcmb(0) for high-z objects.
CO_SLED_CI_fit.py is used to fit CO SLED (LVG) and CI (analytical). run by $ python CO_CI_fit.py Install package using python-pip if package is required.
The fitted SLED and corner plots are in fit_result/.
