Spitzer First Look Survey -- Ancillary MMT/Hectospec Spectral Data
The Spitzer First Look Survey
(FLS) is the initial Director's Discretionary
Time program executed on the observatory. The
extragalactic component is composed of 4 square
degrees of imaging with MIPS and IRAC centered
at J1718+5930. For more information on the
Spitzer First Look Survey, click
here.
Access is provided here to the second
delivery (
v2) of the spectroscopic
survey using the
MMT/Hectospec fiber spectrograph of 24
µm sources selected with the Spitzer Space
Telescope in the FLS (
FLS_HECTOSPEC).
Released are 1296 new redshifts for 24 µm
sources, including 599 with
f
v(24µm) >= 1 mJy. These
data are combined with 291 additional redshifts
for sources from the Sloan Digital Sky Survey
(SDSS). The Hectospec survey includes 1078 and
168 objects spectroscopically classified as
galaxies and QSOs, respectively. These data
accompany the paper, Papovich et al. (2006),
AJ, in press, available at:
http://arvix.org/abs/astro-ph/0512623.
Redshift catalogs and spectra are available
here using
spatial search queries
only, as are the following
browse products, created by IRSA:
MMT/Hectospec spectrum previews and ASCII
spectrum table files (binned and unbinned).
Advanced queries on redshift catalog
columns only may be made using the
Gator query
engine (scroll down to th Spitzer catalog
section). To download all the FLS_HECTOSPEC
data, click

The FLS_HECTOSPEC data coverage is
represented on the
FLS NOAO
Extragalactic -- R band mosaicked image
with overlays above. Catalog source positions
are shown in
cyan for MMT spectra, in
red for SDSS
and MIPS photometry and in
yellow for SDSS
spectra. Click

dataset.
