Notes. The date is in the format year-month-day, DIT stands for detector integration time, NDIT is the number of detector integrations per HWP switch angle and texp is the total on-source exposure time. The parallactic rotation is only indicated for observations performed in pupil-tracking mode. The seeing and coherence time are retrieved from measurements by the DIMM (Differential Image Motion Monitor) and from the MASS-DIMM (Multi-Aperture Scintillation Sensor), respectively.
