The Multiband Imaging Photometer for Spitzer (MIPS) provides long-wavelength capability for the mission in imaging bands at 24, 70, and 160 m and measurements of spectral energy distributions between 52 and 100 m at a spectral resolution of about 7%. By using true detector arrays in each band, it provides both critical sampling of the Spitzer point-spread(More)
We present the discovery of debris systems around three solar mass stars based upon observations performed with the Spitzer Space Telescope as part of a Legacy Science Program, " the Formation and Evolution of Planetary Systems " (FEPS). We also confirm the presence of debris around two other stars. All the stars exhibit infrared emission in excess of the(More)
Retropharyngeal abscess is a rather rare, deep-neck infection of children and may seriously compromise the airway and mimic other diseases. A retrospective review of 17 cases of retropharyngeal abscess presenting to The Children's Hospital, Denver, from 1976 to 1986 was performed. Nine children (56%) had stridor or airway obstruction. Seven patients (41%)(More)
The absolute calibration and characterization of the Multiband Imaging Photometer for Spitzer (MIPS) 70 µm coarse-and fine-scale imaging modes are presented based on over 2.5 years of observations. Accurate photometry (especially for faint sources) requires two simple processing steps beyond the standard data reduction to remove long-term detector(More)
We describe the data reduction algorithms for the Multiband Imaging Photometer for SIRTF (MIPS) instrument. These algorithms are based on extensive preflight testing and modeling of the Si:As (24 µm) and Ge:Ga (70 and 160 µm) arrays in MIPS. The behaviors we describe are typical of state-of-the-art infrared focal planes operated in the low backgrounds of(More)
We describe the data reduction algorithms for the Multiband Imaging Photometer for Spitzer (MIPS) instrument. These algorithms were based on extensive preflight testing and modeling of the Si:As (24 µm) and Ge:Ga (70 and 160 µm) arrays in MIPS and have been refined based on initial flight data. The behaviors we describe are typical of state-of-the-art(More)
We present Spitzer Space Telescope imaging observations at 3.6, 4.5, 5.8, 8.0, and 24 m of the SCUBA submillimeter sources and Jy VLA radio sources in a 5 0 ; 5 0 area in the Lockman Hole East region. Out of the $40 SCUBA/ VLA sources in the field, Spitzer counterparts were detected for nearly all except for the few low-weight SCUBA detections. We show that(More)
Sixty three members of the 100 Myr old open cluster M47 (NGC 2422) have been detected at 24µm with Spitzer. The Be star V 378 Pup shows an excess both in the near-infrared and at 24µm (K − [24] = 2.4 mag), probably due to free-free emission from the gaseous envelope. Seven other early-type stars show smaller excesses, K − [24] = 0.6 − 0.9. Among late-type(More)
