Overheads (TNT Only)

The following overheads should be considered in the time requests:

- Telescope pointing and acquisition: 5 min

- Filter changes: 30s

- Instrument changes: 1 minute

- Flat-Field, Dark: usually included in the calibrations at the beginning and end of the night.

- Other calibrations: consult the NARIT staff

Concerning interruptions (e.g. fixed-time events, transits, occultations, etc), the PI should include in the time request also the time needed to change instrument, point the telescope, and any other overheads as necessary. Note that instrument changes are limited to the M4 rotation. The TNO staff shall not, as a rule, switch off other instruments or disconnect cables as part of the change.
