Table information for 'polcatsmc.data'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: An optical polarimetric catalog for the Small Magelanic Cloud (SMC) is presented. It gives intrinsic and observed polarizations in the V-band for a total of 7207 stars located in the Northeast and Wing sections of the SMC and part of the Magellanic Bridge.
