Techniques for Automated High-Precision Photometry of Sun-like Stars
Tennessee State University operates several Automatic Photoelectric Telescopes (APTs) located at Fairborn Observatory in the Patagonia Mountains of southern Arizona. The APTs are dedicated to photometric monitoring programs that would be difficult and expensive to accomplish without the advantages provided by automation. I describe the operation of two of the telescopes (0.75 and 0.80 m APTs) a...
متن کاملConjugateplane photometry: reducing scintillation in groundbased photometry
High-precision fast photometry from ground-based observatories is a challenge due to intensity fluctuations (scintillation) produced by the Earth’s atmosphere. Here we describe a method to reduce the effects of scintillation by a combination of pupil reconjugation and calibration using a comparison star. Because scintillation is produced by high-altitude turbulence, the range of angles over whi...
متن کاملSpectroradiometric Determination of the Freezing Temperature of Gold
A direct spectroradiometric determination of the temperature of freezing gold was performed by measuring the spectral radiances of a gold blackbody relative to those of a laser-irradiated integrating sphere which was calibrated with absolute silicon detectors and an electrically calibrated radiometer. The measurements were performed at three laser wavelengths near 600 nm, and the temperature of...

سرطانهای جلدی را می توان به انواع پیش بدخیم و بدخیم تقسیم نمود. شایعترین ضایعه جلدی پیش بدخیم، کراتوز آفتابی نام دارد که بصورت ضایعات خشک و دلمه دار جلدی بروز می کنند - لنتیگو آفتابی یک ضایعه پیش بدخیم دیگرن است که بصورت لکه های قهوه ای و صاف (غیر برجسته روی پوست مشاهده می شوند) ضایعات پیش بدخیم در صورت عدم درمان می توانند بدخیم شوند.
متن کاملAngular Spectroradiometric Field Measurements for Precision Farming Purposes
Precision farming requires information about the present status of the vegetation canopy. Remote sensing products can provide such information. The general investigation approach is based on the evaluation of remotely sensed data by the inversion of physical backscatter models and coupled growth models. The presented paper describes the measurement strategy, developed for the establishment of a...
