Abstract:
We demonstrate an approach to determine spectral energy distribution
(SED) templates that are accurate to the 1% level from the visible
through the infrared for nearby (unextincted) solar-type stars. Our
approach is based only on measurements of Teff, log(g), and M/H and
the use of standard theoretical SED models. The success of this
approach confirms that the existing absolute calibration is likely to
be accurate to this level throughout this spectral range. We then
demonstrate how to measure and correct for extinction, allowing
extension of this calibration approach to faint levels (and more
distant stars). We provide template SEDs in digital form for 11
G-dwarf stellar calibrators.
Description:
NIRSpec on JWST was used to observe several flux standard stars during
the commissioning period and also as part of the Cycle 1 calibration
program.
We observed the three open clusters with WFCAM on the UKIRT in queue
mode on 2016 October 11, 25, and 26, November 11, and December 29,
(UTC). This is the same instrument, pipeline, and telescope used for
the UKIDSS survey for the infrared JHK bands.
