Asteroids for Calibration of MIR Spectroscopy |
Below is a table of asteroids with radii greater than 50 km. Approximate coordinates are given every 0.5 years. For accurate coordinates the observers will need to obtain orbital elements (e.g. from the JPL Horizons website).
The observer should pick the best asteroid for the time of the semester during which the observation is most likely to be performed. Asteroids move rapidly across the sky at times; thus it is possible that the observer will decide to substitute for the asteroid picked by the PI.
Asteroids are useful telluric standards for medium-to-high resolution N and Q band spectroscopy because they have no narrow spectral features. They may have broad (FWHM~1um) features with strengths as much as 5% of the continuum (see e.g. Lim et al. 2005 Icarus, 173, 385 [ADS abstract]).
At opposition a typical asteroid is ~1.5 AU from earth. An asteroid of radius 100 km at this distance will have an N magnitude of ~-0.2 mag and a Q magnitude of ~-3.0 mag. A program that uses the echelle should select asteroids at least 75 km in radius, as smaller asteroids require longer integration times. Experience with observations at the short end of the N band window (~7.7 microns) has shown that asteroids tend to be fainter at these wavelengths; PIs planning observations at short wavelengths should pick the largest object possible.
