As I was debriefing Louis about the major changes to the pydarm_H1.ini pyDARM model parameter file (LHO:68514), I caught myself on this line:
Parameter                                         Version bcb959d8           Updated Version            aLOG           Notes

omc_meas_p_whitening_uncompensated_whiteningoff   44500.68 : 44575.08        [intentionally blank]                      - Fixed conceptual error that 44 kHz poles are present when whitening is OFF
[...]


Somehow, in the rush of things on Friday, I had convinced myself that these 44 kHz poles were a part of the switchable whitening stage for the D2200215-style OMC DCPD Whitening filter, and thus when the whitening stage is switched OFF, these 44 kHz poles would not be present.

This is incorrect: the 44 kHz poles are a part of the fixed differential receiver stage of the D2200215's D2200044 whitening filter board, present regardless of whether the *actual* switchable whitening stage is ON or OFF..

As such, I've copied the pole values for DCPD A and DCPD B that live in the omc_meas_p_whitening_uncompensated_whiteningon, and the update here is:
Parameter                                         Version df913213           Updated Version            aLOG           Notes

This minor fix has been pushed, such that the new version has git hash 83764fcb.
