Eggen PV photometry in NGC 7492
Listed in IVOA Registry (Virtual Observatory)
Photometry of NGC 7492, a very faint, well resolved cluster, shows that it has a colour-magnitude relation similar in form to that of a typical globular cluster.
Description
A well defined but sparsely populated red giant branch is present, along with a horizontal branch, blue stars, and variables. The distance modulus, 17.17, and the distance 27.2kpc., are obtained.
The colour excess appears to be negligible. The integrated photographic absolute magnitude is -4.84. The star density in the cluster is unusually low, being approximately 0.06 stars per cubic parsec for stars brighter than +2.5 absolute magnitude.
