An updated catalog of M33 clusters and candidates: $UBVRI$ photometry,
  and some statistical results
  We present $UBVRI$ photometry for 392 star clusters and candidates in the
field of M33, which are selected from the most recent star cluster catalog. In
this catalog, the authors listed star clusters' parameters such as cluster
positions, magnitudes and colors in the $UBVRIJHK_s$ filters, and so on.
However, a large fraction of objects in this catalog do not have previously
published photometry. Photometry is performed using archival images from the
Local Group Galaxies Survey, which covers 0.8 deg$^2$ along the major axis of
M33. Detailed comparisons show that, in general, our photometry is consistent
with previous measurements. Positions (right ascension and declination) for
some clusters are corrected here. Combined with previous literature, we
constitute a large sample of M33 star clusters. Based on this cluster sample,
we present some statistical results: none of the M33 youngest clusters ($\sim
10^7$ yr) have masses approaching $10^5$ $M_{\odot}$; roughly half the star
clusters are consistent with the $10^4$ to $10^5$ $M_{\odot}$ mass models; the
continuous distribution of star clusters along the model line indicates that
M33 star clusters have been formed continuously from the epoch of the first
star cluster formation until recent times; there are $\sim 50$ star clusters
which being overlapped with the Galactic globular clusters on the color-color
diagram, and these clusters are old globular clusters candidates in M33.
