Use methane mixing ratio bias_corrected in harp with python

[wannh]

Hi, sir, from my methane dataset it has methane_mixing_ratio and methane_mixing_ratio_bias_corrected dataset, when I use harp to processing the data, how should I know which data was used ? Here is my python code,

I read harp document S5P_L2_CH4 — HARP 1.13 documentation,

my understanding is the default data used is methane_mixing_ratio, what if I want to use methane_mixing_ratio_bias_corrected, how should I edit the code? many thanks

From this question, Questions on Cloud_fraction in L2_NO2 and S5P_L2_CLOUD
I thought the python code shoud be like this, and it works
