@HenningSE I guess we are good to merge if we make some decisions on the FDC correction. : )

[dachengx]

Or I guess we can also implement the FDC-corrected z later.

@HenningSE Do you think this PR is in good shape to merge? Or what are the ongoing or pending development?

[HenningSE]

Hi @dachengx, sorry I think I missed your question a few days ago. As far as I can tell, the FDC correction was basically copy and paste from the existing straxen code.

From my perspective the PR can be merged! Thanks for you help!

Hey @HenningSE . The z_obs_ms in peak_corrections.py is only corrected by electron_drift_time_gate. So the FDC correction is not done. But anyway we can do it later and I believe this PR was meant to fix bugs.

I will merge it after the test passes.
