Standard Photometric Systems
Standard star photometry dominated the second part of the th century reaching its zenith in the s It was introduced to take advantage of the high sensitivity and large dynamic range of photomultiplier tubes compared to photographic plates As the quantum e ciency of photodetectors improved and the wavelength range extended further to the red standard systems were modi ed and re ned and deviation...
متن کاملHigh-intensity vapor lamp for biological research.
A vapor arc light source has been adapted to the study of the lethal action on bacteria of near-ultraviolet (UV) and visible light. Its use makes possible much shorter exposure times than could be obtained from previously available sources. The output of radiant energy is sufficient to provide a fairly detailed action spectrum for lethality in the long-UV and visible region without the addition...
متن کاملThe NIST Detector-Based Luminous Intensity Scale
The Système International des Unités (SI) base unit for photometry, the candela, has been realized by using absolute detectors rather than absolute sources. This change in method permits luminous intensity calibrations of standard lamps to be carried out with a relative expanded uncertainty (coverage factor k = 2, and thus a 2 standard deviation estimate) of 0.46 %, almost a factor-of-two impro...
متن کاملThe photometric estimation of luciferase in luminous bacterial cells.
Recent studies have shown that t,he luminescence of luminous bacteria under certain conditions responds to ionizing radiation instantaneously (1) and, under other conditions, responds to doses as low as 500 rads (2). The intensity of the luminescence is proportional to the rate of th(, luciferase reaction taking place in viva. Thus radiation effects both on the metabolic system supporting the l...
متن کاملA Test of Photometric Redshifts for X-ray Luminous Galaxies
We test the effectiveness of photometric redshifts based upon galaxy spectral template fitting for X-ray lumininous galaxies, using a sample of 29 sources that were detected by Chandra in the Hubble Deep Field and flanking fields. We find that sources with quasar-dominated spectra are easily identified, and that photometric redshifts are robust for the rest of the sources in our sample. Specifi...
