An Exposure Time Calculator (ETC) is available for ULTRASPEC, from V.Dhillon’s web page.
For spectroscopy, an ETC is not yet available. As a guideline, the limiting sensitivity of MRES is tentatively estimated at V=14.5 (1 hour) due to lack of an auto-guider.
Applicants are strongly encouraged to contact the OPD staff to find out the latest status of each instrument.
