Abstract: |
In the current era of precision astronomy, a complete sky background
model is crucial, especially as the telescopes become even larger in the
next decade. Such a model is needed for planning observations as well as
understanding and correcting the data for the sky background. We have
developed a sky model for this purpose, and it is the most complete and
universal sky model that we know of to date. It covers a wide range of
wavelengths from 0.3 to 30 micron up to a resolution of 1,000,000 and is
instrument independent. Currently it is optimized for the telescopes at
Cerro Paranal and the future site Cerro Armazones in Chile. Our sky
model includes several components necessary to describe the sky
background flux, such as scattered moonlight and starlight, zodiacal
light, airglow emission and continuum, thermal emission from the
telescope and lower atmosphere, and scattering and absorption within the
Earth's atmosphere. Each component was designed with the latest
knowledge and results in the field and was thoroughly checked with
archival ESO data. Our sky background model
will be a valuable asset
for astronomical observatories and the community. |
