Brazil and China have a long-term joint space based sensor program called China-Brazil Earth Resources Satellite (CBERS). The most recent satellite of this program (CBERS-4) was successfully launched on 7 December 2014. This work describes a complete procedure, along with the associated uncertainties, used to calculate the in-flight absolute calibration coefficients for the sensors Multispectra...

The exclusive reaction γγ → f f̄γ is considered as the possible calibration process on the linear photon collider. We analyse the energy spectrum and total cross section dependence on the detector parameters at various initial beam helicities. 2 T. V. Shishkina, V. V. Makarenko

Abstract We present a recalibration of the photometric systems in Pantheon+ sample Type Ia supernovae (SNe Ia) including those SH0ES distance-ladder measurement H 0 . utilize large and uniform sky coverage public Pan-STARRS stellar photometry catalog to cross calibrate against tertiary standards released by individual SN surveys. The most significant updates over “SuperCal” calibration used for...

Effective May 5, 2003, Landsat-5 (L5) Thematic Mapper (TM) data processed and distributed by the U.S. Geological Survey (USGS) Earth Resources Observation System (EROS) Data Center (EDC) will be radiometrically calibrated using a new procedure and revised calibration parameters. This change will improve absolute calibration accuracy, consistency over time, and consistency with Landsat-7 (L7) En...

Lidar and radar observations from CALIPSO and CloudSat missions have allowed the development of methods to determine atmospheric parameters [1, 2]. Total aerosol optical depth (AOD) and cloud liquid water path have thus been derived at the scale of the lidar or radar footprint using AMSR-E wind speed information [3, 4], or the combination of lidar and radar observations using ocean surface echo...

Camera calibration requires the identification of points in an image that correspond to known locations in the scene. These are typically determined through the use of a calibration pattern designed to facilitate feature localisation. We present in this paper a novel method of generating patterns such that each subregion is individually identifiable by its cross ratio. The method aims to minimi...

We propose a novel calibration method for catadioptric systems made up of an axial symmetrical mirror and a pinhole camera with its optical center located at the mirror axis. The calibration estimates the relative camera/mirror position and the extrinsic rotation and translation w.r.t. the world frame. The procedure requires a single image of a (possibly planar) calibration object. We show how ...

Camera calibration plays an important role in the domain of the analysis of sports video. Considering soccer video, in most cases, the cross-points can be used for calibration at the center of the soccer field are not sufficient, so this paper introduces a new automatic camera calibration algorithm focus on solving this problem by using the properties of images of the center circle, halfway lin...

BACKGROUND Models of the dynamics of interstitial fluid-based continuous glucose sensors imply a variable sensor deviation from reference blood glucose (BG), depending on both sensor calibration procedure and BG dynamics. These effects could have a significant effect on the cross-interpretation of nonidentical accuracy studies. METHODS Hyperinsulinemic euglycemic and hypoglycemic clamps were ...
