Notes. The column designations have the following meaning: HJD – heliocentric Julian Day of the beginning of exposure; FLUX – flux resulting from aperture photometry, in ADU; XCEN – x coordinate of the centroid of the stellar profile in the coordinate frame of a subraster; see Eq. (1), in pixels; YCEN – the same for the y coordinate; CCDT – temperature of CCD detector (in °C); JD – Julian Day of the beginning of observation; it can be useful for identifying frames, which are labelled with JD; FLAG – a 0/1 flag indicating if for a given frame the aperture was fully rendered within the subraster (1) or not (0); PSFC = PSFC1 – the first blurring parameter, see Appendix B; PSFC2 – the second blurring parameter; see Appendix B; RTSC – a parameter related to RTS in columns; see Appendix B, RTSP – a parameter related to RTS in pixels within the optimal apertures, see Appendix B, APER0 – median value of background in a difference image.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
