Abstract:
A survey for compact clusters with a dimension of 10pc order was
conducted in an area of about 500 square arc-minutes of the south-west
part of the M31 disk, making use of the high-resolution capability of
Suprime-Cam. Photometry in the B, V and R broad-bands, and in the R*
medium-band centered around Hα with varying apertures was
carried out for about 1200 targets, which are related to about 300
compact objects detected in the survey. The results for 101 prominent
compact objects are presented as photometric catalogues and
morphological atlases, separately for samples with and without strong
Hα emission.
Description:
We used the M31 frames that were secured during the verification
period of Suprime-Cam in 1999 July.

Note (3): Morphological codes, also in file "codes.dat", are the following:
s1 = one dominant star with surrounding components
s2 = concentrated multiple stars in a common envelope
s3 = compact star aggregation
c1 = concentric isophote less steep than that for normal stars
c2 = loose round isophote profile
c3 = elliptical or irregular loose isophote profile
c4 = as c3 but with multiple peaks in a common envelope
c5 = as c4 but its peaks are diffuse
d = profile resembling that of a disk galaxy
g = profile resembling that of a globular cluster
rs1 = one star surrounded by compact emission nebulosity
rs2 = compact emission nebulosity with one faint star
rs3 = one star with companion surrounded by emission nebulosity
rs4 = one star with diffuse emission envelope
rc1 = a few stars in a common emission envelope
rc2 = stellar group in a common emission envelope
rc3 = star cluster in a common emission envelope.
