Description:
Tables 5, 7, and 8 contain the data of the CCD photometry of the three
open star clusters. We added the numbering systems of previously
published papers to the tables. Table 5 contains the data of NGC 4103
with stellar numbers from Wesselink (1969MNRAS.146..329W 1969MNRAS.146..329W); Table 7 the
data of NGC 5281 with the numbers of Moffat & Vogt
(1973A&AS...10..135M 1973A&AS...10..135M); Table 8 the data of NGC 4755 with the numbering
system according to Arp & van Sant (1958AJ.....63..341A 1958AJ.....63..341A). In Tables
12, 13, and 14 we present relative proper motions of the three
clusters (in the same sequence). For NGC 4103 the table contains the
information of an entire Carte du Ciel field of 2 degrees square, for
the other two clusters, a small subfield had to be selected
beforehand. The numbers of Arp & van Sant (1958AJ.....63..341A 1958AJ.....63..341A) are
encrypted in the following way: Numbers <100 stand for the stars A to
Q, the first digit of the numbers >100 represents the quadrant. The
two final digits are the running numbers in the notation of Arp & van
Sant (1958AJ.....63..341A 1958AJ.....63..341A).

Global notes:
Note (G1): Notations:
Arp & van Sant, 1958AJ.....63..341A 1958AJ.....63..341A, NGC 5286 NNN in simbad
Moffat & Vogt, 1973A&AS...10..135M 1973A&AS...10..135M, NGC 5281 NNN in Simbad
Wesselink, 1969MNRAS.146..329W 1969MNRAS.146..329W, NGC 4103 NNN in Simbad
Note (G2):
For NGC 4103 and 5281, north is at the bottom and east to the right,
for NGC 4755 north is to the right, east up. These are the "original"
pixel coordinates as determined from the CCD images by DAOPHOT, therefore
the strange orientation. (0,0) is the lower left pixel of the field which
is centered on the cluster. For NGC 4103, three different fields were
observed, for the other clusters two fields each. The coordinates of the
other field(s) were shifted according to their location.
The scale is 0.375 arcsec/pix (NGC 4103, NGC 5281) and
0.3 arcsec/pix (NGC 4755), respectively.
