J/A+A/513/A6        NOT survey of subdwarf B stars         (Ostensen+, 2010)

The purpose of the programme was to significantly extend the number of rapidly pulsating sdB stars to better understand the properties of this new group of variable compact stars. Candidates were selected initially from the HS and HE surveys, but were supplemented with additional objects from other surveys. Short sequences of time-series photometry were made on the candidates to determine the presence of rapid pulsations. Description: The table contains all the sdB stars observed during the NOT survey that were not identified as pulsators. It provides coordinates, details of the photometric sequences, and on the variability for each object. File Summary:

Note (1): The mma units are milli-modulation amplitudes, i.e. 1E-3 of the Fourier amplitudes of a light-curve in normalised intensity units. One mma translates to a peak-to-peak amplitude of two millimodulation intensity (mmi) units in the light curve. Note (2): Targets flagged as NOV (not observed to vary) have Amax<3.7xSigma. The remaining targets are discussed individually in the paper.
