Correct elife at the last in corrected_areas

[dachengx]

What does the code in this PR do / what does it improve?

We corrected PI after elife in #1247, so that got a lot of nan cs2_area_fraction_top.

Can you briefly describe how it works?

Now we correct the cS2 in the order of:

1. S2(x,y)
2. SEG and EE
3. PI
4. elife

Can you give a minimal working example (or illustrate with a figure)?

Please include the following if applicable:

• Update the docstring(s)
• Update the documentation
• Tests to check the (new) code is working as desired.
• Does it solve one of the open issues on github?

Using run_id 051806, comparing the result of old and new versions:

----------
old nan cs2 22.9%
new nan cs2 22.9%
difference cs2 8.8%
mean abs difference cs2 1.7e-03
----------
old nan cs2_area_fraction_top 22.9%
new nan cs2_area_fraction_top 1.5%
difference cs2_area_fraction_top 45.9%
mean abs difference cs2_area_fraction_top 2.7e-08
----------
old nan cs2_area_fraction_top_wo_picorr 0.0%
new nan cs2_area_fraction_top_wo_picorr 1.5%
difference cs2_area_fraction_top_wo_picorr 28.9%
mean abs difference cs2_area_fraction_top_wo_picorr 1.6e-08
----------
old nan cs2_wo_elifecorr 0.0%
new nan cs2_wo_elifecorr 0.0%
difference cs2_wo_elifecorr 0.0%
mean abs difference cs2_wo_elifecorr 0.0e+00
----------

new nan cs2_wo_picorr 0.0%
difference cs2_wo_picorr 98.1%
mean abs difference cs2_wo_picorr 4.8e+03
----------

The difference on cs2_wo_picorr is as expected.

Thanks Dacheng. Indeed, I loaded the same run and most events now have non-nan values for cs2_area_fraction_top, except for 6 events which I believe to be blinded events. I also use xedocs to set config and the photoionization correction is as expected. The code looks much cleaner.

I thinkcs2_area_fraction_top and cs2_area_fraction_top_wo_elifecorr are always the same, also true for cs2_area_fraction_top_wo_timecorr and cs2_area_fraction_top_wo_picorr, but I guess it's more convenient to have all values there so analysts are not required to know all of this.

Also the description of cs2_wo_* is consistent with code. Very good!

The left caveat is that we should also update PeakCorrectedAreas https://github.com/XENONnT/straxen/blob/2e9eaaa7e146e8a19573849293aa796ac46630ee/straxen/plugins/peaks/peak_corrections.py, and solve #1257. But let's put it in another PR.
