The determination of the perception probabilities for magnitude
and DCV can be found in the full analysis method papers

Perception corrections are better expressed in corrections
on LM, since this also includes the population index. An
observer seeing more meteors is typically sees more fainter
ones. This advantage slims if the shower provides a low
population index (many bright meteors compared to faint ones).
See

for a few recent determinations of the perception corrections.
