This must be done even if the same calibration star can be used for all the science targets. For example, if you need to observe and flux-calibrate six targets in a filter that is not supported by the calibration plan of the instrument, you need to provide six OBs for photometric calibration to allow for the case in which each target is observed on a different night. You should submit enough OBs to cover that situation. You should assume that your science OBs will be executed completely independently of each other, possibly on different nights, and take into account that no user-supplied OB (for a science or a calibration target) will be executed more than once.

User-supplied OBs for calibration are only executed once. Their execution time is then charged to your time allocation. If this is not the case, you must provide additional OBs for calibration appropriate for each mode not included in the Calibration Plan.

Please check carefully in the User Manual whether or not the instrument configurations that you plan to use are included in the instrument's Calibration Plan. Calibration Plans for each instrument and mode are described in detail in their corresponding User Manual, and their execution times are not charged to the Service Mode programmes.

The most commonly used observing configurations of each instrument are calibrated by means of the Observatory's Calibration Plan.
