are in arc seconds with positive east and positive north
respectively.

Notes:
1. This single night sequence, based on field photometry by Arne
Henden, has nominal external errors of 0.02 magnitude, apart from
star #13 which has larger errors due to its faintness.
2. The three brightest stars are saturated and their magnitudes are
only approximate. Star #1 has reliable Tycho-2 photometry: V=9.76
+/-0.03.
