Most European qualifying round payouts are currently listed at a flat $99k, including most UCL payouts, with the exception of playoff round loser payouts.
UEL payouts are a flat $278k.
All UECL payouts are 99k, no loser payouts for the last qualifying round
It is very easy to see these are very wrong. Wikipedia has updated data for 22-23 for UEL and UECL and lots of other sites have data for 21-22 for UCL, which can't be far enough off that preliminary round appearance has dropped from 250k to 99k
