... The standard lbn cal diode was compared to the standard diode. Using the standard diode value and the insertion loss the lbn cal value was computed every 25 MHz from 1200 MHz to 1600 Mhz. ... After the measurement, the insertion loss from the standard diode to the output of the coupler was measured over the frequency range 1200 to 1400 Mhz. ... The major uncertainty in the measurement is in the standard diode ENR and the insertion loss of the waveguide transition. ... freq [Mhz] . ...

Ref: ALMA band 1 horn measures Date: 27/08/2002 Technical note ALMA band n.1 horn measurements Author: Renzo Nesti Summary This document is intended to give pattern and return loss measurements of the ALMA band n.1 horn (31.3-45 GHz) produced by CLOEMA and designed by MECSA and Arcetri. ... Because the measurements have been made by rotating the horn under test on the expected phase centre we conclude that the estimation of the phase centre position does agree well with tests. ...

... The visible power a source emits in all directions is measured in lumens. ... Solid Angle- . ... The solid angle of a light cone is the projected area of the cone divided by the total surface area of the sphere. A solid angle is measured in steradians, where 1 steradian corresponds to the solid angle su btended by a cone of unit slant height and unit projected area. ... Luminous intensity is the flow of luminous energy, or lumens, per steradian. ... This is the rate of flow (lumens) per unit area. ...

... This paper presents an overview of the CENTERFIT image centering algorithm library currently under development in the IRAF system. ... The centering algorithms employed by these applications must satisfy a wide range of efficiency and accuracy requirements, and function robustly on data sets spanning a broad wavelength, resolution, and signal-to-noise regime. This paper presents an overview of CENTERFIT, a library of 1-D and 2-D centering algorithms currently under development in the IRAF system. ...

... STIS . ... In a space environment, CCD detectors accumulate radiation damage, which over time leads to increasing dark current, more hot pixels, and reduced charge transfer efficiency. After twelve years on orbit, the effects of such radiation damage on the STIS CCD have become substantial. ... Since in a CCD, charge must be transferred many times before reaching the readout register, even a small decrease in CTE can have a large effect on the measured count rate near the center of the detector. ...

Sternberg State Astronomical Institute, Moscow, 119899, Russia, pugach@sai.msu.ru Summary: New satellite measurements of the lunar-surface radiation temperature were used to construct the spatial angular function of thermal radiation of the Moon in the infrared (10.5-12.5 micron) spectral range. ... These thermal anomalies are observed only in the limited range of phase angles. ...
