Coordinates: 16 19 44.4368 +46 18 48.119 B: 3.74 V: 3.89 (B-V): -0.15 Spectral Type: B5IV

The plot compares the Version-2 spectrum with the Version-1 spectrum of each star. The title gives the star name and the offset from slit center in pixels. Version-1 spectra are plotted in light blue-green. Version-2 spectra are plotted in black if the measured offset from slit center is less than 0.9 pixels, and in red when the offset is greater than 0.9 pixels (to indicate that the slit throughput correction is unreliable).
