For each of the 52,989 entries in the redshift catalog, we provide a corresponding one- and two-dimensional spectrum. The spectra are grouped below in tarballs according to slitmask number. For DEEP2, each slitmask was observed for approximately 1 hour (3 x 1200sec), utilizing the 1200 lines/mm grating centered at 7800Å and the OG550 order-blocking filter with 1” slitwidths. The raw DEIMOS data were reduced using the DEEP2 DEIMOS spec2d pipeline.
The 1-d and 2-d spectra are packaged in [gzipped] FITS files with the following filename coventions: spec1d.mmmm.nnn.id.fits.gz and slit.mmmm.nnnB/R.fits.gz, where mmmm = the slitmask number, nnn = the slit number, id = the DEEP2 object ID number given in the redshift catalog (OBJNAME), and B/R = the Blue or Red half of the 2-d spectrum (the DEIMOS data are reduced chip-by-chip with each spectrum spanning two CCDs). Each of the tarballs unpacks to produce directories denoting the mask number and observation date (e.g. 5000/2008apr08/) with the 1-d and 2-d spectra inside. Each tarball is roughly 1.5-2GB in size. For some objects/slits, there will only be a single 2-d “slit” file (either B or R); this typically occurs when half of the spectrum curves off of the DEIMOS CCDs.
With the move to a new website and plan for serving the data, the spectra are no longer available via wget. Sorry. Instead, the tarballs are available to download via Google Drive:
