The DEEP2 EGS data includes high-resolution DEIMOS spectra for more than 10,000 sources spanning 75 DEIMOS slitmasks. Each slitmask was observed for ~1 hour with some variation depending on seeing, weather conditions, etc. All observations utilize the 1200 lines/mm grating centered at 7800E and the OG550 order-blocking filter with 1\" slitwidths. The raw DEIMOS data were reduced using the DEEP2 DEIMOS spec2d pipeline (version v1.0.4). The 1-d and 2-d spectra for the entire dataset are available in the following tarballs.

This plot shows the right ascension and declination for each DEEP2 target (black) and those with positive ACS identifications (yellow). The redshifts were measured using emission lines (Balmer Series, [NII], [SII], [OIII], [OII]) and the Calcium (H, K and other ) absorption features. Each redshift measurement was assigned a “quality” identifier according to at least two independent measurements . In the center the quality distribution is shown. Quality codes were assigned on the basis of a set of criteria: a value of 4 is assigned to a “rock-solid” z measurement obtained from a spectrum with at least two clear features. A value of 3 indicates a good z value, with a 90% probability to be correct. At least two features are still required but ID is more doubtful than Q=4. A value of 2 indicates a non-usable measurement for the present catalog but the spectrum will be later revisited because a useful z value might be extracted from it. Q=1 means that the redshift is not usable and the data will never yield one. Q=-1 is reserved for stars. This plot shows the z-magnitude diagram: magnitudes were obtained from Sextractor
