XMM-Newton (cross)-calibration

SPIE Proceedings, 2004
ESA's large X-ray space observatory XMM-Newton is in its fifth year of operations. We give a general overview of the status of calibration of the five X-ray instruments and the Optical Monitor. A main point of interest in the last year became the cross-calibration between the instruments.

A Novel Radiometric Cross-Calibration of GF-6/WFV With MODIS at the Dunhuang Radiometric Calibration Site

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
To obtain more abundant target information for vegetation remote sensing research, the wide field of view (WFV) of the GaoFen-6 (GF-6) satellite utilizes eight bands, including four new bands.

The cross-calibration array: a technique to cross-calibrate the energy scales of cosmic-ray experiments using a portable radio array

Proceedings of 38th International Cosmic Ray Conference — PoS(ICRC2023), 2023
The sources of the highest energy cosmic-rays are still a mystery. One way to try to understand these sources is to measure the energies and composition of cosmic rays and build models that describe their energy spectrum. However, at the highest energies, energy scales between experiments are inconsistent.

Radiometric Cross-calibration of KOMPSAT-3A with Landsat-8 [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
In this study, Cross calibration was conducted at the Libya 4 PICS site on 2015 using Landsat-8 and KOMPSAT-3A. Ideally a cross calibration should be calculated for each individual scene pair because on any given date the TOA spectral profile is ...

Absolute Flux Calibration of the IRAC Instrument on the Spitzer Space Telescope using Hubble Space Telescope Flux Standards [PDF]

, 2011
The absolute flux calibration of the James Webb Space Telescope will be based on a set of stars observed by the Hubble and Spitzer Space Telescopes. In order to cross-calibrate the two facilities, several A, G, and white dwarf (WD) stars are observed ...

INTEGRAL Cross-calibration Status

, 2004
The status of the INTEGRAL cross-calibration is presented for a standard X-ray astronomy source, the Crab Nebula, as well as for some weaker sources. The relative flux normalization for the different INTEGRAL instruments is discussed together with spectral shape features.
