The New Eclipsing Cataclysmic Variable SDSS 154453+2553
, 2011 The cataclysmic variable SDSS154453+2553 was recently identified in the Sloan Digital Sky Survey. We obtained spectra and photometry at the MDM Observatory, which revealed an eclipse with a 6.03 hour period.

Infrared Variability of the Gliese 569B System [PDF]
, 2012 Gliese 569B is a multiple brown dwarf system whose exact nature has been the subject of several investigations over the past few years. Interpretation has partially relied on infra-red photometry and spectroscopy of the resolved components of the system.

, 2008 Photometric calibration observations are routinely carried out with all ESO imaging cameras in every clear night. The nightly zeropoints derived from these observations are accurate to about 10%. Recently, we have started the FORS Absolute Photometry Project (FAP) to investigate, if and how percent-level absolute photometric accuracy can be achieved ...

MIPS 24-160 micron photometry for the Herschel-SPIRE Local Galaxies Guaranteed Time Programs [PDF]
, 2012 We provide an overview of ancillary 24, 70, and 160 micron data from the Multiband Imaging Photometer for Spitzer (MIPS) that are intended to complement the 70-500 micron Herschel Space Observatory photometry data for nearby galaxies obtained by the Herschel-SPIRE Local Galaxies Guaranteed Time Programs and the Herschel Virgo Cluster Survey.

TRIPPy: TRAILED IMAGE PHOTOMETRY IN PYTHON [PDF]
, 2016 Photometry of moving sources typically suffers from a reduced signal-to-noise ratio (S/N) or flux measurements biased to incorrect low values through the use of circular apertures.

Wide-field stellar photometry in Piwnice Observatory [PDF]
arXiv, 2007 In this paper research projects based on the wide-field CCD photometry performed in Piwnice Observatory are discussed. The used telescopes, as well as dedicated software pipeline for data reduction are presented. The prospects for collaboration between Polish and Bulgarian institutes in the field of wide-field photometry are also discussed.

Correction factor for real-time determination of wood dust mass concentration by photometric method
Drvna Industrija, 2009 Samples of wood dust were collected in the working environment of wood machining processes for the purpose of determining correction factors for measuring mass concentration of wood dust by photometric method.

Tycho Astrometry and Photometry [PDF]
Symposium - International Astronomical Union, 1986 The HIPPARCOS Star Mappers were designed to determine the satellite attitude by observation of stars with known positions. ESA has now enhanced them so that the continuous photon counts from two photo multipliers with B and V response will be recorded.

Annals of Applied Biology, EarlyView.This study evaluated the population dynamics of stubby root nematodes (SRN) in field rotations with cover crops and the subsequent effect of this rotation on sugar beet quality and quantity attributes. It was clear that the SRN densities under field conditions are influenced by multiple factors, such as the type of cover crops grown, soil disturbance ...
