Arcsecond Positions of UGC Galaxies
We present accurate B1950 and J2000 positions for all confirmed galaxiesin the Uppsala General Catalog (UGC). The positions were measuredvisually from Digitized Sky Survey images with rms uncertaintiesσ<=[(1.2")2+(θ/100)2]1/2,where θ is the major-axis diameter. We compared each galaxymeasured with the original UGC description to ensure high reliability.The full position list is available in the electronic version only.

The CfA Redshift Survey: Data for the NGP +36 Zone
We have assembled redshifts for a complete sample of 719 galaxies withm_zw_ <= 15.5 in the declination range 32.5^deg^ <= δ <=38.5^deg^ and right ascension range 8^h^ <= α <= 17^h^. Wehave determined morphological types for all galaxies in the magnitudelimited sample by direct inspection of the POSS-O plates. 576 of theredshifts are measurements from Mount Hopkins, and 405 are newredshifts. We also include new redshifts for 77 fainter galaxies in thesame strip.

A redshift survey of low-surface-brightness galaxies. I - The basic data
Initial results from a 21 cm redshift survey of 375 very low surfacebrightness galaxies contained in the Uppsala General Catalog of Galaxiesare presented. The selection criteria and detection statistics as afunction of the sample optical properties are fully discussed. Theredshift distribution for the sample exhibits a pronounced peak at 5000km/s, corresponding to the well-studied Perseus-Pisces supercluster. Theoverall detection rate was 65 percent, and the bulk of the detectionsare genuine low surface brightness spiral galaxies, may with linewidthsin excess of 300 km/s, as opposed to true dwarf galaxies. It is arguedthat most of the nondetections are unlikely to be gas-poor dwarfs, butinstead are galaxies with velocities beyond 10,000 km/s. Taken as awhole, the sample demonstrates that optical surface brightness is notnecessarily a reliable indicator of intrinsic luminosity or mass.
