Notes. Date UT is given for the beginning of an observing run. X shows the changes of the target's airmass during a run. Nobs is the number of useful scientific exposures. texp is the exposure time. Г is the median number of exposures per minute. pnr is the photometric noise rate (Fulton et al. 2011) in parts per thousand (ppth) of the normalised flux per minute of the observation.
