Abstract:
The Century Survey strip covers 102°2 within the limits
8.5h≤RA≤16.5h, 29.0°≤DE≤30.0°, equinox B1950.0. The strip
passes through the Corona Borealis supercluster and the outer region
of the Coma cluster. Within the Century Survey region, we have
measured 2410 redshifts that constitute four overlapping complete
redshift surveys: (1) the original Century Survey of 1728 galaxies
with Kron-Cousins (Kron, White, & Gascoigne, 1953ApJ...118..502K 1953ApJ...118..502K)
Rph≤16.13 covering the entire strip (Geller et al.,
1997AJ....114.2205G 1997AJ....114.2205G, hereafter OCS), (2) 507 galaxies with Rph≤16.4
in right ascension range 8h32min≤RA≤10h45min, equinox B1950.0,
(hereafter DCS) (3) 1251 galaxies with absorption- and K-corrected
RCCDc≤16.2 (where "c" indicates "corrected") covering the right
ascension range 8.5h≤RA≤13.5h, equinox B1950.0 (Brown et al., 2001,
Cat. J/AJ/122/714, hereafter RCS), and (4) 1255 galaxies with
absorption- and K-corrected VCCDc≤16.7 also covering the right
ascension range 8.5h≤RA≤13.5h, B1950.0 (Brown et al., 2001, Cat.
J/AJ/122/714, hereafter VCS). All these redshift samples are more
than 98% complete to the specified magnitude limit. We derived samples
1 and 2 from scans of the POSS1 red (E) plates calibrated with CCD
photometry. We derived samples 3 and 4 from deep V and R CCD images
covering the entire region. We include coarse morphological types for
all the galaxies in sample 1. The distribution of (V-R)CCD for each
type corresponds appropriately with the classification.
