Abstract / Description:In this paper we present results of a pilot
study to use imaging data from the Sloan Digital
Sky Survey (SDSS) to search for low surface
brightness (LSB) galaxies. For our pilot study we
use a test sample of 92 galaxies from the Impey
et al. catalog distributedover 93 SDSS fields of
the Early Data Release (EDR). Many galaxies from
the test sample are either LSB or dwarf
galaxies. To deal with the SDSS data most
effectively, a new photometry software was
created, which is described in this paper. We
present the results of the selection algorithms
applied to these 93 EDR fields. Two galaxies from
the Impey et al. test sample are very likely
artifacts, as confirmed by follow-up imaging.
With our algorithms we were able to recover 87 of
the 90 remaining test sample galaxies, implying
a detection rate of ~96.5%. The three missed
galaxies fall too close to very bright stars or
galaxies. In addition, 42 new galaxies with
parameters similar to the test sample objects
were found in these EDR fields (i.e., ~47%
additional galaxies). We present the main
photometric parameters of all identified galaxies
and carry out first statistical comparisons. We
tested the quality of our photometry by
comparing the magnitudes for our test sample
galaxies and other bright galaxies with values
from the literature. All these tests yielded
consistent results. We briefly discuss a few
unusual galaxies found in our pilot study,
including an LSB galaxy with a two-component disk
and 10 new giant LSB galaxies.
