Abstract:
We present two wide-field (∼5'x3.5'), diffraction-limited
(λ/D∼0.5" at 10µm), broadband 10 and 20µm images of the
Orion Nebula, plus six 7-13µm narrowband images of the BN/KL
complex taken at the 3.8m UKIRT telescope with the MPIA MAX camera.
Description:
The wide-field maps presented in this paper were obtained combining
observations made in 1998 November and 2000 December at the 3.8m
United Kingdom Infrared Telescope (UKIRT) on Mauna Kea, Hawaii.

Note (1): A "c" indicates that the identification number 499 is used in the
list of Muench et al. (2002, Cat. J/ApJ/573/366) for two different
stars (both are binaries).
Note (2): Derived from our final mosaic with typical accuracy ∼0.5",
accurate enough to unambiguously identify each source.
Note (3): A "d" indicates sources nr. 84 and 87 are unresolved in the Q-band.
Note (4): Remark is:
a = From O'Dell & Wen (1994ApJ...436..194O 1994ApJ...436..194O);
b = From Hayward, Houck, & Miles (1994ApJ...433..157H 1994ApJ...433..157H).

Note (1): The BN peak coordinates are (J2000)=05:35:14.10-05.0:22:22.7 a
nominal pixel scale of 0.26" constant across the field, a rotation
angle of -0.8° east of north, as measured on the same night for
the wide field area project. The BN center was set at the pixel
position (64.2, 82.2) and measured using a centroid procedure with 5
pixel (1.3") radius.
