Note that this field has been calibrated by Henden; I'm
pretty sure Simonsen has a chart available.
The star in question shows in the .dat file as
RA (J2000) DEC V B-V verr bverr
218.6795450 -0.786095 14.463 0.915 0.204 0.041
so is relatively red compared with the variable. The photometric
errors indicate variability, though I haven't inspected the
individual nights nor the images to see if there might be other
problems.
