The measurement of the acceptance angle of an optical fiber, which is the maximum angle at which the core of the fiber will take in light that will be contained within the core. Taken from the ...

We reduced the data using different pipelines and performed aperture photometry with the help of custom routines in order to obtain the light curves. The fit of the light curves (1.5–2.5 mmag rms), ...

Completely updated, this second edition gives a broad review of astronomical photometry to provide an understanding of astrophysics from a data-based perspective. It explains the underlying principles ...

The previous chapter described the various aberrations and, in Eqs. 5.1 and 5.2, indicated the manner in which the various "orders" of aberrations varied with the aperture and the field angle of the ...

These predictions are used to measure the differential photometry between binary members to an accuracy ... Equation (6) represents the piston‐removed phase covariance on a circular aperture in the ...

Originally equipped for visual viewing, 4x5 film photography, photomultiplier photometry, and glass-plate stellar spectroscopy, the 24-inch now utilizes CCD electronic technology to achieve the same ...

We detail each camera lens on a separate row for clarity. Specs include the number of megapixels, aperture, focal length, sensor size, zoom type and methods of stabilization and focusing system.

Digital Chat Station is back with another leak about the upcoming nubia Z70 Ultra – the phone will upgrade the 35mm camera that is a trademark of the series with a ...

VSAR (Venus S-Band Synthetic Aperture Radar): It aims to search ... SPAV (Solar Occultation Photometry): SPAV will measure ...
