These pages contain images and data for old, young and candidate clusters in M31. Pages with images and data for each candidate cluster are provided in the hope that they will be of use to the community. However, they were produced via scripts and should be used with caution (if you notice any errors or have any questions, please let me know).

INDIVIDUAL CLUSTER IMAGES

This study is based optical images from the Sloan Digital Sky Survey ( SDSS ) and near infra-red images from the Wide Field Camera (WFCAM) on the UK Infra-red Telescope ( UKIRT ). The original fits images from these M31 surveys are currently available from the SDSS Supplemental Archive and the The WFCAM Science Archive.

CLUSTER CATALOG/ PHOTOMETRY

These tables provide ugriz and K-band photometry for M31's clusters and candidates with SDSS/WFCAM images. These data are from table1 of Peacock et al. (2010). The classification of each source is given in column 4 and should be used to select genuine clusters from the table.

m31gc.info  -description of the columns

m31gc.dat  -the complete catalog, table1 from Peacock et al. (2010)

  m31gc.1.dat  -only confirmed old clusters from the main catalogue

  m31gc.2.dat  -only unclassified candidate clusters from the main catalogue

  m31gc.3.dat  -only young clusters from the main catalogue

STRUCTURAL PARAMETERS

This table contains structural parameters for all confirmed old clusters. The parameters are from Peacock et al. (2009) and were obtained from fitting PSF convolved King models to these WFCAM images (using a code developed by Chris Waters).

m31gc.1.struct.dat  -confirmed old clusters from the main catalogue, which have estimates of their structural parameters

This is the original data table from Peacock et al. 2009a (table1), but is superseded by the above table: m31gc.struct.old.dat
