Abstract:
We present a new catalog of HII regions in M31. The full disk of the
galaxy (∼24kpc from the galaxy center) is covered in a 2.2deg2
mosaic of 10 fields observed with the Mosaic Camera on the Mayall 4m
telescope as part of the Local Group Galaxies survey.
Description:
The images were taken at the 4m Mayall telescope with the Mosaic CCD
Camera between 2000 August and 2002 September and comprise Hα
and R-band mosaics of 10 overlapping fields across the disk of M31.
