[vsnet-chat 2345] Sequence near SN 99ee

[bas@mailhost.lowell.edu (Brian Skiff)]

     The calibration sequence that Berto mentions as being near SN 1999ee is
evidently the one by Bunclark et al., which I copy below from my photometric
reference file along with the full citation.  I note that USNO-A2.0 (not A1.0)
blue and red magnitudes for these moderately bright stars seem to be reasonably
close to "truth" as defined by this sequence, with only the usual scatter of
+/- 0.3 mag. or so and no large zero-point offset.
