Description
A new low-dispersion objective-prism search for low-redshift
(z<0.045) emission-line galaxies (ELGs) has been carried out by the
Universidad Complutense de Madrid using the Schmidt Telescope at the
Calar-Alto Observatory. This is a continuation of the UCM Survey, which
was performed by visual selection of candidates in photographic plates
via the presence of the Hα+[N II]λ6584 blend in emission.
In making this new list we have applied an automatic procedure, fully
developed by us, for selecting and analyzing ELG candidates on the
digitized images obtained with the "Machine Automatique a Mesurer pour
l'Astronomie" (MAMA). The analyzed region of the sky covers
189deg2 in nine fields near RA=14h and 17h, DE=25°. The
final sample contains 113 candidates. Special effort has been made to
obtain a large amount of information directly from our uncalibrated
plates by using several external calibrations. The parameters obtained
for the ELG candidates allow us to study the statistical properties of
the sample. (1 data file).
