2.4.3 Fill Out an Astronomical Observation Template
Select an AOT from the Observation menu. The instrument configuration and
integration time parameters are entered in the AOT form. In Cycle-4 nine
distinct AOTs are available for Spitzer observations. We provide complete
worked examples of seven AOT types in the chapters that follow. An
example of the Total Power and MIPS Enhanced Photometry AOT may be
included in a future edition of the Cookbook.
IRAC Mapping:
- The IRAC AOT is used for simultaneous
imaging at 3.6, 4.5, 5.8 and 8.0 microns, over the two
fields of view. See
§4 (deep imaging) and
§10 (wide-field, shallow
imaging).
IRS Staring Mode Spectroscopy:
- The IRS staring mode is
used for low-resolution, long-slit spectroscopy
from 5.3 to 40 microns and high-resolution spectroscopy
from 10 to 37 microns. It also returns images from the
IRS Peak-Up array. See §6.
IRS Spectral Mapping:
- The IRS Spectral Mapping AOT is used
to configure a grid of map positions around a central target
position and obtain spectra at each position
IRS Peak-Up Imaging:
- The IRS Peak-Up Imaging AOT is used to
obtain images from the Peak-Up array, which has a field-of-view
of approximately 1 arcminute square and two filters covering
and
. As of CP-2 this mode is
now available. See §8.
MIPS Photometry/Super Resolution:
- The MIPS Photometry and
Super Resolution AOT is used for imaging photometry at 24, 70
and 160 microns. See §5.
MIPS Scan Map:
- The MIPS Scan Map AOT is used for large
field maps at 24, 70 and 160 microns. The maps are constructed
using slow telescope scanning, combined with motion compensation
using a cryogenic scan mirror. Maps are built up of 5.1
arcminute wide strips between 0.5 and 6 degrees in length. See
§9.
MIPS Spectral Energy Distribution:
- The MIPS Spectral Energy
Distribution AOT is used for very low resolution
spectroscopy covering 55-95 microns using the MIPS 70 micron Ge:Ga
array. See §12.
MIPS Total Power Mode:
- The MIPS Total
Power Mode AOT provides zero-level-reference observations at
,
, and
for absolute brightness of
extended sources.
