Notes:

1. This single night sequence should have zero-point errors around 
0.02 magnitude. 

2. There are two bright stars near the edge of this field. One is at 
06h 14m 48.3S +15d 22' 24" and has a reliable Tycho-2 magnitude of
V=10.18+/-0.04. The other, near the southwest corner at 06h 14m 58.0S 
+15d 37' 01" has a reliable Tycho-2 magnitude of 9.14+/-0.02.

3. Star #1 is saturated and its magnitude and colour are approximate. 

It has a semi-accurate Tycho-2 magnitude of 11.42+/-0.11. It should 
be used for guidance only until an accurate magnitude is determined.

4. A check of Digital Sky Survey images shows that V344 Ori is about
magnitude 18.8 at minimum.
