Abstract:
Intrigued by the initial report of an extended luminosity distribution
perpendicular to the disk of the edge-on Sc galaxy NGC 5907, we have
obtained very deep exposures of this galaxy with a Schmidt telescope,
large-format CCD, and intermediate-band filters centered at 6660 Å
and 8020 Å. These two filters, part of a 15-filter set, are custom
designed to avoid the brightest (and most variable) night skylines. As
a result, our images are able to go deeper with lower sky noise than
those taken with broadband filters at similar effective wavelengths:
e.g., 0.6 e- arcsec-2 s-1 for our observations versus 7.4 e-
arcsec-2 s-1 for the R-band measures of Morrison et al.
(1994AJ....108.1191M 1994AJ....108.1191M). In our assessment of both random and systematic
errors, we show that the flux level where the errors of observation
reach 1 mag arcsec-2 are 29.00 mag arcsec-2 in the 6660 Å image
(corresponding to 28.7 in the R band) and 27.4 mag arcsec-2 in the
8020 Å image (essentially on the I-band system)
