arr = det.raw.calib(evt, **kwa)

dark correction - pedestals subtraction using constants of ctype pedestals from DB
common mode correction depending on cmpars or constants of ctype common_mode from DB
gain correction with constants from DB for ctype pixel_gain
mask is not applied by default (see below)

common_mode(raw-peds)/gain

Mask In lcls2 mask is derived and applied separately as explained in Area detector mask examples or Detector interfase in LCLS-II.

...

cmpars=None - use constants from DB
cmpars[1] = 0 - OFF
both cmpars=None and common_mode constants are missing in DB - common mode correction is OFF

Spreadsheet below contains comments on detector specific application
