Abstract (from CDS):

We present ISO SWS (AOT6) observations of the protostellar object RAFGL 7009S. This source is particularly interesting for the characterisation of chemistry arising from grain surfaces and mantles, since the solid state features of many simple molecules such as H2O, CO, CO2, 13CO2 and CH4 are detected, together with weaker features not yet unambiguously identified. Gas phase H2O, CO2, CH4 and CO can also be seen superimposed on the much broader solid state features. We derive an estimate for the gas phase temperature around 50K. The gas to solid ratios of these simple molecules is found to be ≥0.2 for H2O, ∼0.2 for CH4, and an order of magnitude lower for CO2. We discuss the possible implications for interstellar chemistry in such objects.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
