Stellar Photometry with the Optical Monitors [PDF]
International Astronomical Union Colloquium, 1993 AbstractThe Optical Monitors are small optical telescopes which will fly on board of the X-ray satellites SPECTRUM-X-GAMMA (JET-X experiment) and XMM. Their main scientific applications are the simultaneous observations (imaging) in the optical and UV band of the optical counterparts of X-ray sources, with limiting magnitudes of aboutmv=22(JET-X) and ...

Optical and Infrared Photometry of the nearby SN 2017cbv [PDF]
The Astrophysical Journal, 2018 Abstract On 2017 March 11, the DLT40 Transient Discovery Survey discovered SN 2017cbv in NGC 5643, a Type 2 Seyfert Galaxy in the Lupus Constellation. SN 2017cbv went on to become a bright Type Ia supernova, with a V max of 11.51 ± 0.05 mag.

Optical and Radio Surface Photometry of NGC 891 [PDF]
Symposium - International Astronomical Union, 1990 A general correlation between the radio and optical continuum surface brightness has been found in the edge-on galaxy NGC 891. This suggests that the relativistic electrons are produced/accelerated in the vicinity of evolved stars or stellar remnants which have a spatial distribution similar to old disk stars.

Evaluation of Multiangle Absorption Photometry for Measuring Aerosol Light Absorption [PDF]
, 2005 A new multiangle absorption photometer for the measurement of aerosol light absorption was recently introduced that builds on the simultaneous measurement of radiation transmitted through and scattered back from a particle-loaded fiber filter at multiple

The photometry of optical instruments [PDF]
Transactions of the Optical Society, 1922 The use of a portable surface-brightness photometer of the polarisation type for the measurement of the fraction of the incident light transmitted by an optical instrument or reflected by a mirror or system of mirrors, and for the measurement of the relative brightness of different parts of the field of view of an optical instrument, is described.
