Some comments on the paper.
  The Balmer series of hydrogen are "lines", not "bands".
  I don't see a lot of need for Figure 1; you repeat the
TASS V-band magnitudes in Figure 2 anyway.
  In Figure 2, it looks like there is a significant
difference in V between Koppelman and TASS near maximum.
You might comment on that in the text.
  I don't understand this 4750A feature in the spectrum;
it looks like you picked this as the "peak" of the energy
distribution as well, and that is probably not correct.
You should also indicate how you flux-calibrated the spectrum.
With a spectrum, you should be able to determine the spectral
class better than with a crude Te fit; line strengths help.
  What is the source for the coordinates?
  How did you obtain the V-magnitude calibration?  Did
Doug calibrate the comp stars and you use these to obtain
the differential V magnitude?  If he calibrated the comp
stars, you should present the calibration.
  In general, looks good.
