GLIMPSE Spitzer and Ancillary Data
GLIMPSE I/II/3D Observations (l=+65deg to Galactic Center)
GLIMPSE I/II/3D Observations (Galactic Center to l=-65deg)
You can get a close-up map of a region by clicking on the maps above,
or by typing a coordinate below. The background images, from
ISSA, are shown on a galactic coordinate grid;
the images cover 15 x 85 degrees, about the galactic center (coords: 0 0 ga). GLIMPSE I image data sky coverage is shown above as footprints
in
red for the resolution mosaics
(1.2 arcsec
pixels) and
yellow for the high resolution
mosaics (0.6 arcsec pixels). GLIMPSE II sky coverage is shown
in
cyan for the native resolution mosaics
and
magenta for the high resolution
mosaics. GLIMPSE 3D image data sky coverage currently available is
in
black for the native resolution mosaics
and
green for the high resolution
mosaics. Additional GLIMPSE 3D coverage
within 10 degrees of Galactic center will be added in an upcoming
release.
Spitzer Data from the "Galactic Legacy Infrared Midplane Survey
Extraordinaire" (
GLIMPSE) Legacy I, II and 3D Projects, are available
here using spatial and visualization tools (last updated February 2009). For
GLIMPSE I, II and 3D, two sets of 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 (0.6 arcsec aka "high resolution" and
1.2 arcsec pixels aka "native resolution") for science and visualization needs.
The FITS headers contain relevant information from both the SSC pipeline
processing and the GLIMPSE processing such as IRAC frames included in the
mosaicked image and coordinate information.
The GLIMPSE I & II native resolution images (1.2" pixel) come in two versions: v2.0 and v3.5.
The v3.5 mosaic images match instrumental background variations between
the IRAC frames. Instrument artifacts such as full array pull-up, first
frame effect and frame pull-down are mostly removed from these images.
Since this processing may be removing real sky variations the v2.0 (1.2" pixel)
mosaics are also provided since these do not have
the background matching.
GLIMPSE I
-
Fifth delivery (DR5, FINAL) from
GLIMPSE I; all previous GLIMPSE I image deliveries
are superseded by DR5. Appendix A in the GLIMPSE I
data products document discusses the differences between the v2.0
GLIMPSE I processing and the superseded v1.0 data products.
-
The coverage of the GLIMPSE I 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).
-
GLIMPSE I image data sky coverage is shown above as footprints
in red for the native resolution mosaics
(1.2 arcsec
pixels) and yellow for the high resolution
mosaics (0.6 arcsec pixels).

PS;
additional README files can also be
accessed.
GLIMPSE II
-
Final delivery from GLIMPSE II. The nominal
GLIMPSE II Survey region is l= -10 deg to 10 deg (details in table
below). These data products include all epochs of the
GLIMPSE II survey region. They also include the Galactic center
data from the General Observer (GO) program GALCEN (PI: Stolovy,
Program ID=3677
search Spitzer Data at IRSA), as well as GLIMPSE I data at the
boundary of the surveys (at l=10 deg and l=349 deg).
| longitude | latitude |
|---|
| 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 |
-
GLIMPSE II image data sky coverage is shown above as footprints
in cyan for the native resolution mosaics
(1.2 arcsec
pixels) and magenta for the high resolution
mosaics (0.6 arcsec pixels).

accessed.
GLIMPSE 3D
-
Four cumulative deliveries (DR1, DR2, DR3, and January 2009
from 2007-2009) from GLIMPSE 3D.
-
The coverage of the GLIMPSE 3D Survey provides a vertical
extension of GLIMPSE I or GLIMPSE II style coverage to higher Galactic
latitudes in selected longitude ranges. GLIMPSE3D adds vertical extensions,
generally up to |b| < 3deg, but up to |b| < 4.2 deg
in the center of the Galaxy.
-
GLIMPSE 3D image data sky coverage currently available is shown above as footprints
in black for the native resolution mosaics
(1.2 arcsec
pixels) and green for the high resolution
mosaics (0.6 arcsec pixels).
-
Please
note that approximately 80% of the GLIMPSE 3D survey data have been made available so far;
a complete delivery will be released at a later date.
-
Please see GLIMPSE 3D Delivery Document v1.2: PDF or
PS;

accessed.
- Users who have accessed the GLIMPSE 3D Archive: please read the erratum.
These datasets are part of the
Enhanced Products
data from the Spitzer Science Center
(
SSC).
GLIMPSE I DR5 can also be found at the staging location as
20070416
(Spring '07, includes data patch on Jan. 11, 2008).
GLIMPSE II can also be found there as
20080418.
GLIMPSE 3D can be found spread across four download locations:
20070717,
20080130,
20080721 and
20090114.
You can also download any of the GLIMPSE I, II and 3D
images, headers and 3-color previews
directly. GLIMPSE I Spring '07, GLIMPSE II Spring '08 and
GLIMPSE 3D (2007-2008)
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 and 3D image "
cutouts" using IRSA's
Cutouts Service,
which is a general tool to create single or multiple small FITS
(and JPEG) image cutouts of datasets archived at IRSA.
