Abstract:
A new survey of star clusters in the southwest field of the M31 disk
based on the high-resolution Subaru Suprime-Cam observations is
presented. The UBVRI aperture CCD photometry catalog of 285 objects
(V≲20.5mag; 169 of them identified for the first time) is
provided. Each object is supplemented with multiband color maps
presented in the electronic edition of the Astrophysical Journal
Supplement. Seventy-seven star cluster candidates from the catalog are
located in the Hubble Space Telescope archive frames.
Description:
The Suprime-Cam survey of star cluster-like objects was conducted in
the southwest (SW) field of the M31 disk, centered at
RA(J2000)=0h40.9m and DE(J2000)=+40°45'.

Note (1): Of aperture centers in the USNO-B1.0 catalog system.
Note (2): the 5 objects saturated in the I-band images have 99.999
Note (3): In the LGGS fields F6-F9.
Note (4): Diameter of circular aperture or major axis length of elliptical
aperture. Elliptical apertures (ratio of minor to major axis; position
angle of the major axis, calculated counterclockwise from the North
direction) are used for objects KW102 (0.75; 120°) and KW141
(0.70; 30°).
Note (5): 77 total objects in the HST instrument frames.
Frame identification is:
W = WFPC2 (71 objects)
A = ACS (6 objects)
Note (6): The cross-identification stars by a number related to:
1 = The Revised Bologna Catalogue of M31 globular clusters and candidates
V.3.2, July 2007 (Galleti et al., 2007, Cat. J/A+A/471/127):
69 objects (in Simbad: G is SKHB, V is [V62], B is Bol, BH is M31GC)
KW128 is identified with V203 and KW129 - with V202, however,
coordinates are offset;
KW271 and KW273 are identified as one object - G099.
2 = Krienke & Hodge (2007, Cat. J/PASP/119/7): "KHM31" numbers are given
only for 24 objects not listed in '1' (KHM31 NNN in Simbad).
KW154 has two identifications: KHM31-79 and KHM31-80.
3 = Kodaira et al. (2004, Paper I, Cat. J/PASJ/56/1025): "KWC" and "KWE"
numbers are given for 58 objects.
KW063 is identified with KWE09 and KW095 - with KWE19, however,
center coordinates and apertures are slightly different.
