Notes. Instruments that provided photometric time series (Obs ID), wavelength range (wavelength), corresponding start (obsstart), and end dates (obsend), total time base of the reduced data set (time base, T), Rayleigh frequency resolution (1/T), number of data points (N), residual noise in the amplitude spectrum after prewhitening all frequencies (res. noise) and Nyquist frequency (fNyquist). ( * ): The January 2017 BHr data set was only used to fill the gap of the BTr data set, hence was not analyzed by itself. The residual noise level (res. noise) is calculated over the complete range relevant for δ Scuti pulsations from 0 to 100 d−1.
