The molecular spectrum lines data include mainly ammonia and water masers lines at 1.3cm band,
as well as formaldehyde and recombination lines at 6cm band observed towards both our Galactic
plane and nearby molecular clouds and star-forming regions.
The SPM4 Catalog contains absolute proper motions, celestial
coordinates, and B,V photometry for 103,319,647 stars and galaxies
between the south celestial pole and -20 degrees declination. The
catalog is roughly complete to V=17.5. It is based on photographic and
CCD observations taken with the Yale Southern Observatory's
double-astrograph at Cesco Observatory in El Leoncito, Argentina.
The zCOSMOS redshift survey used 600h on the VIMOS spectrograph spread over
five observing seasons (2005-2009) to obtain spectra of about 20,000 galaxies
selected to have Iab < 22.5 across the full 1.7 deg2 of the COSMOS field.
This part, "zCOSMOS-bright", was designed to yield a high and fairly uniform
sampling rate (about 70%), with a high success rate in measuring redshifts
(approaching 100% at 0.5 < z < 0.8), and with sufficient
velocity accuracy
(about 100 km/s) to efficiently map the environments of galaxies down to the
scale of galaxy groups out to redshifts z ~ 1.
