includes a sequence derived from USNO-A2.0 data. The common stars
are:
ID Henden AAVSO
V B-V
2 13.269 0.858 133
3 14.037 0.767 142
5 14.695 1.104 147
6 15.216 0.652 151
7 15.507 0.648 153
2. This sequence is based on photometry obtained on a single night,
and the errors are expected to be +/-0.02 magnitude.
