General rules for user contributions required for allocated observing time

User contributions

The table below applies to the current (i.e. effective for P74) user contributions that are required from PIs, contributing to the operational cost of executing the observations in service mode, and for programs acquiring external access to NOT.

Note that the numbers for external programs are increasing slightly for P75 - the new fees will be updated here imminently, well before the deadline of the Call for P75 programs, but the numbers below can and should be used as a guideline.

The numbers refer to the amount of euros per full observing night.

	Access for external programs	5620
	Service-mode user contribution	600
	Additional user contribution for override/queue mode	150
	Fast-track programs for external users	1670

Note that the numbers when expressed per hour vary slightly between Summer and Winter semesters.
