Time series of constant star UCAC4 600-107181 (color index B − V = 0.39 mag) from 1181 scans of 606 photographic plates over 32 years, covering data from blue-sensitive (pg, shown as blue dots) and yellow- and red-sensitive (pv, shown as red dots) plates from APPLAUSE DR3. Plates were classified based on known emulsions and reliable data (see Appendix A for details about the plates used in this figure). Upper panel: series of color terms determined by RMS fitting. Lower two panels: calibrated B magnitudes of the star, differing in that panel 3 includes 80 plates of the two emulsions Kodak IIa-O and Kodak 103a-D, which were only exposed in the Lippert-Astrograph. The calibrated V and B magnitudes are identical, except for a shift of the color index.
