Robert Modic asked me if it would be possible to extract a photometric
sequence from my SV Sge frames to extend the existing sequences down
to fainter magnitudes, since the variable is currently very faint.
Given below is a reasonably good sequence down fainter than the variable.
The differential magnitudes between stars should be good, but since I
only took data on one photometric night, there may be a zero point error
for the sequence of a few hundredths. I've tried to select stars of
comparable color in the sequence, but I could not find any bright stars
that weren't red. Coordinates are J2000. Star 04 is the 149 comparison.
