Identifications (numbers or letters) are from NAS.VSS. Star names
and positions (rounded to 0s.1 in R.A. and 1" in Decl.) are from
Tycho (TYC), Tycho Input (TIC) and Guide Star (GSC) catalogues. V-
and VT-magnitudes and (B-V)-colours with corresponding uncertainties
sV, sVT and s(B-V) in V, VT and B-V are from TYC and TIC.
Differential CCD-measurements of faint stars were made by D. Nogami,
Ouda station, Kyoto University (Ouda). The Ouda observations were
made on 1998 Apr 4.43 UT using TYC 3723-0065 as a calibration star.

Data from Hipparcos Catalogue [numbers, V-magnitudes and (V-I)-
colours]: 1 = HIP 20380(V=5.91, V-I=+0.13), 2 = HIP 20308 (V=7.08,
V-I=+1.41), 3 = HIP 20306 (V=7.66, V-I=+0.18), 4 = HIP 20314
(V=7.93, V-I=+0.26), A = HIP 20276 (V=8.24, V-I=+1.71). The
catalogues were accessed from Centre de Donn馥s astronomiques de
Strasbourg (CDS), and we wish to thank CDS for this service.
 
We have prepared two charts for CI Cam. They are available as GIF
