A Comparison of Laboratory and ALMA Spectra
The hot core of Orion KL (R. A. = 05hr 35m 14.35s, Dec = -05o 22’ 35” (J2000)) [1]. Preliminary data for a single pixel (of a 1024 x 1024 array of pixels) centered on the hot core of Orion KL is used in this comparison.
Here we will consider how well simple models based on CES can simulate this ALMA spectrum for a number of the astrophysical ‘weed’ molecules [6]. Issues that are addressed include the completeness of the laboratory spectroscopic basis in the context of this real astrophysical example and how well the simplest LTE models of the interstellar medium can account for the astrophysical spectrum.
