VISIR Catography of Orion - BN
Coordinator: Lagage, Petr-Gotzens, Pantin, Rouan
Abstract:
This imaging programme aims at obtaining a large MID-IR map of the high-mass star forming region Orion BN-KL at highest possible spatial resolution. Unlike many other sites of high-mass star formation BN/KL is in close proximity, at only $\sim$450pc distance, and therefore offers an unique opportunity to study its structure and individual sources at great detail.
Data:
Program is available and data products can be downloaded
Observing strategy:
Observations are performed at three different wavelengths. Nine partly overlapping pointings shall be observedat 8.6 (PAH1) and 11.25 (PAH2) micron, respectively. At 17.65 micron only 3 pointings are defined. PSF reference stars are observed frequently. Due to the crowded nature of the region a large nod throw was defined, which implies the use of the VISIR template VISIR_img_obs_GenericChopNod.
