Abstract:
This paper extends synthetic photometry to components of binary star
systems. The paper demonstrates accurate recovery of single star
photometric properties for four photometric standards, Vega, Sirius,
GD153, and HD209458, ranging over the HR diagram, when their model
synthetic spectra are placed in fictitious binary systems and
subjected to synthetic photometry processing. Techniques for
photometric distance determination have been validated for all four
photometric standards.
Description:
For Sirius, the file spectrum consists of three segments: an IUE
spectrum over the range 1150Å to 1675Å, merged HST spectra over
the range 1675Å to 10000Å, and a special Kurucz synthetic
spectrum over the range 10000Å to 2996860Å.
We use the CALSPEC spectrum for GD153
(http://www.stsci.edu/instruments/observatory/cdbs/calspec). The
spectrum consists of two segments: a merged STIS spectrum covering the
range 1140Å to 10040Å, and a merged NICMOS spectrum covering the
range 10040Å to 24976Å.
For HD209458, our analysis uses the CALSPEC spectrum
(https://github.com/AlLinnell/spectra/). The CALSPEC spectrum consists
of an STIS spectrum covering the range 2905Å to 10150Å; a NICMOS
spectrum covering the range 10150Å to 24920Å, and a synthetic
spectrum covering the range 24920Å to 400000Å.
