Information on Service 'Star clusters and other objects in M31 field'

[Use this service from your browser]

Further access options are discussed below

This catalog contains derived information and access to spectra for a catalog of objects in the field of M31, drawn from the study of star clusters, HII regions, PNe and individual stars in M31 done with Hectospec on the MMT by Nelson Caldwell and a host of others.

For a list of all services and tables belonging to this service's resource, see Information on resource 'Star clusters and other objects in M31 field'

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
