Spitzer Data from the "Galactic Legacy Infrared
Midplane Survey Extraordinaire"
(GLIMPSE) Legacy Project, are available
here using spatial and visualization tools:
GLIMPSE I
-
Fifth delivery (DR5, FINAL)
from GLIMPSE I; all previous GLIMPSEI image
deliveries are superseded by DR5. Appendix A in the GLIMPSEI
data products document
discusses the differences between the v2.0 GLIMPSEI
processing and the superceded v1.0 data products.
-
The coverage of the GLIMPSEI
Survey is l=10-65 deg, 295-350 deg, b=+- 1 deg, plus the Observation
Strategy Validation (OSV) region at about l=284 deg.
-
SSC pipeline data processings S13.2 and later were used
(Reach et al. 2005 calibration).
-
GLIMPSEI image data sky coverage
is shown above as footprints
in red
(3.1x2.4 degree mosaics; 1.2 arcsec pixels) and yellow (1.1x0.8 degree
mosaics; 0.6 arcsec pixels). The
two sets of GLIMPSEI image mosaics are created
using the same input data in all four
Spitzer IRAC
bands (3.6, 4.5, 5.8, 8.0 µm);
they are mosaicked at two different pixel scales for
science and visualization needs.
GLIMPSE II
-
First delivery from GLIMPSE II.
The nominal GLIMPSEII Survey region is l= -10 deg to 10 deg (details in table below). It excludes the Galactic center area from about l=+- 1 deg, b=+-0.75 deg,
which was observed by a GO program (Program ID=3677;
search Spitzer Data at IRSA).
The next release (v2.0 GLIMPSEII processing) will include the Galactic center data.
| longitude (deg) | latitude (deg) |
| 5<l<10 and 350<l<355 | -1<b<1 |
| 2<l<5 and 355<l<358 | -1.5<b<1.5 |
| 0<l<2 and 358<l<360 | -2<b<2 |
-
SSC pipeline processing version used was S12.4 and is not on the same
calibration as the GLIMPSEI S13.2 and later processing. The data used in the
processing is from the September 2005 observations and does not include
the April 2006 observations.
-
GLIMPSEII image data sky
coverage
is shown in the second panel above as
yellow
(1.1x0.8 degree mosaics; 0.6 arcsec pixels),
magenta
(1.1x1.6 degree mosaics; 0.6 arcsec pixels) and
green
(1.1x1.2 degree mosaics; 0.6 arcsec pixels) footprints.
Mosaics of each band are made for larger areas,
with twice the pixel size (1.2 arcsec pixes), and are
shown in the same panel, as
red
(3.1x2.4 degree mosaics; 1.2 arcsec pixels),
black
(3.1x3.45 degree mosaics; 1.2 arcsec pixels) and
cyan
(3.1x4.5 degree mosaics; 1.2 arcsec pixels)
footprints.
These datasets are part of the
Enhanced Products data from the Spitzer
Science Center (SSC).
GLIMPSEI DR5 can also be found at the staging location as
20070416
(Spring '07, includes data patch on Jan. 11, 2008). GLIMPSEII can also be found there as
2007Jun.
You can also download any of the
GLIMPSE I & II images, headers and
3-color previews directly. GLIMPSE I & II Spring '07
source catalogs and archives are
available using IRSA's Gator
Catalog Search Engine, which allows for complex search
queries. IRSA serves additional Legacy Spitzer-related
data. Also available are GLIMPSE I & II
image "cutouts"
using IRSA's
Cutouts Service, which is a general tool to create single or multiple small FITS
(and JPEGs) image cutouts of datasets archived at IRSA.
