Abstract:
We report on a search for faint (R total magnitude fainter than 21)
and low surface brightness galaxies (R central surface brightness
fainter than ∼24) (fLSBs) in a 0.72x0.82deg2 area centered on the
Coma cluster.
We analyzed deep B and R band CCD imaging obtained using the CFH12K
camera at CFHT and found 735 fLSBs. The total B magnitudes, at the
Coma cluster redshift, range from -13 to -9 with B central surface
brightness as faint as 27mag/arcsec2.
Description:
The observations are described in Adami et al. (2006, Cat.
J/A+A/451/1159 and we only reproduce the salient points in this
section. The Coma field was observed in April 1999 and April 2000 with
the Canada-France-Hawaii 3.6m telescope using the CFH12K camera.
Images were acquired using B, V, R and I Johnson-like filters.
