J/AJ/129/1534    Mid-IR photometry in the Orion Nebula         (Robberto+, 2005)

The Orion nebula in the mid-infrared. Robberto M., Beckwith S.V.W., Panagia N., Patel S.G., Herbst T.M., Ligori S., Custo A., Boccacci P., Bertero M. <Astron. J., 129, 1534-1563 (2005)> =2005AJ....129.1534R
ADC_Keywords: Photometry, infrared ; Interstellar medium ; Infrared sources Keywords: infrared: general - ISM: individual (Orion Nebula) - methods: data analysis - planetary systems: protoplanetary disks - stars: formation 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); b = From Hayward, Houck, & Miles (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.
