ABSTRACT.Aperture Photometry Tool (APT) is software for astronomers and students interested in manually exploring the photometric qualities of astronomical images. It is a graphical user interface ...

Aperture photometry requires two measurements: one of the star (the aperture) and the other of a ring of sky (the annulus) around the star.

In a nutshell Scientists identified over 500 planetary nebulae in the Sculptor galaxy, 20 times more than previous surveys, using the MUSE instrument, but the distance estimate they produced was ...

ABSTRACT.We have devised an aperture photometry pipeline for data reduction of image data from the Taiwanese-American Occultation Survey (TAOS). The photometry pipeline has high computational ...

For images at each wavelength, aperture photometry was performed after subtracting the sky background. The aperture corrections were further applied at each wavelength based on the corresponding ...

The 24-inch Boller & Chivens f/8 Cassegrain was installed in the dome of Sommers-Bausch Observatory in 1973. Originally equipped for visual viewing, 4x5 film photography, photomultiplier photometry, ...

To help Joe Public make sense of this 1.5TB data deluge, COSMOS-Web has thoughtfully provided a full aperture and model-based photometric catalog.
