Asteroids as far-infrared photometric standards for ISOPHOT
Asteroids are used as far-IR calibrators for the imaging photopolarimeter ISOPHOT on board the Infrared Space Observatory ISO. For the 10 selected objects we compiled a large uniform database1 of 678 individual observations, ranging from 7–2 000μm. Applying a new thermophysical model to the observations we derived thermal properties of the selected asteroids, based on spin-vector solutions, dir...
متن کاملImprovements in the Nist Calibration Service for Thermal Transfer Standards
We report on multiple improvements made in the calibration services offered for thermal converters and thermal transfer standards in the ac-dc Difference Standards and Measurement Techniques Project at NIST during the past year. The major improvement in this calibration is the increased efficiency made possible by the consolidation of three disparate calibration services – low voltage thermal t...
متن کاملThermal infrared and optical observations of four near-Earth asteroids
We present thermal infrared photometry and spectrophotometry of four Near-Earth Asteroids (NEAs), namely (433) Eros, (66063) 1998 RO1, (137032) 1998 UO1, and (138258) 2000 GD2, using the United Kingdom Infrared Telescope (UKIRT) in 2002. For two objects, i.e.: (433) Eros and (137032) 1998 UO1 quasi-simultaneous optical observations were also obtained, using the Jacobus Kapteyn Telescope (JKT). ...
متن کاملCalibration of uncooled thermal infrared cameras
The calibration of uncooled thermal infrared (IR) cameras to absolute temperature measurement is a time-consuming, complicated process that significantly influences the cost of an IR camera. Temperaturemeasuring IR cameras display a temperature value for each pixel in the thermal image. Calibration is used to calculate a temperature-proportional output signal (IR or thermal image) from the meas...
متن کاملThe Mauna Kea Observatories Near - Infrared Filter Set . III . Isophotal Wavelengths and Absolute Calibration
The isophotal wavelengths, flux densities, and AB magnitudes for Vega (a Lyr) are presented for the Mauna Kea Observatories near-infrared filter set. We show that the near-infrared absolute calibrations for Vega as determined by Cohen et al. and Mégessier are consistent within the uncertainties, so that either absolute calibration can be used.
