How can I update Cycle 0 absolute fluxes to the Butler-JPL-Horizons 2012 model standards?

Cycle 0 data reduction was done using CASA versions 3.3 and 3.4, which use the Butler-JPL-Horizons 2010 models to set the flux model for solar system objects. The fluxes of science targets were then bootstrapped from these solar system object measurements and models. With the wealth of new information now available from telescopes like Herschel, along with more detailed models of some of the more prevalent atmospheric spectral lines in solar system objects, the models were updated for the CASA 4.0 release. The new models are called Butler-JPL-Horizons 2012 and represent the current best understanding from published or publicly available work. The differences between the two sets of models are typically a few to 20%, with a significant outlier for Venus at Band 9 (38%). Whether the change is important for a specific dataset is highly dependent on individual science goals and which solar system object was used. | |
