As is the case for transit
photometry, if this wobble occurs regularly, then we might reasonably conclude that the gravitational tug of an orbiting planet is responsible.
The most frequently used methods to measure [Na.sub.+] and [K.sub.+] in the clinical laboratory is emission
photometry and ion-specific potentiometer electrodes (Henry, 1991).
By measuring eclipse times and supplementing these with
photometry obtained with the 1.3m MDM telescope on Kitt Peak some years before when the system was quiescent by our co-workers, Prof Joe Patterson and Jonathan Kemp of the Center for Backyard Astrophysics, we determined [P.sub.orb] as 84.8min.
Therefore, at least at this range of detection distance, the data indicate that the effect of color on detection distance is such that a red veiling stimulus must be 1.6 times more luminous (in terms of photopic
photometry) than a blue veiling stimulus.
Further, I obtained access to the
photometry of all of the stars observed by Hipparcos [2].
Rennie said: "The botanical
photometry system is used in the orange production industry in Florida to pick up on the early warning signs of stressed trees.
Photometry and measuring of focus once performed by conventional mirror boxes now are carried out by reading information picked up the imaging sensor directly.
It was only later that the company introduced its first product utilizing its signature technology, ratiometric
photometry. The Pipette Calibration System employs ratiometric
photometry, which is based on taking absorbance ratio readings from two standardized dyes at the same time, to verify the volume dispensed from handheld pipettes and automated pipette systems.
There are several methods of glucose measurement sensing: infrared spectroscopy, reflectance
photometry, and amperometry.
Poor Tara Fitzgerald, who plays the white-coated Dr Eve Lockhart, gets the worst of it, with "a microspectra
photometry and chromatography test" all in one sentence.
Topics covered include light and color, vision and perception, fixtures and
photometry and LEED Design and economics.
A run time self-tuning function increases reading performance with a built-in
photometry calculation.
