... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

... The air just sit there and doesn't get stirred. ... Normally, the air is hottest near the ground and gets cooler as you go up. ... If it weren't for the temperature profile, convection wouldn't occur: Because the temperature decreases with altitude, cold air sits on top of hot air, allowing convection. ... The air above the ground is hot, the air above the water is cold. ... The land cools down faster than the sea, so the air above the ground is colder than the air above the water. ...

ST-ECF Technical Instrument Report WFC3-2009-04 The cross dispersion profiles of the WFC3 grisms H. Kuntschner, H. Bushouse, M. KЭmmel, J. R. Walsh April 30, 2009 ABS TRACT This document summarizes the analysis of the cross-dispersion profile width for the three grisms of the WFC3. For the IR grisms, the cross dispersion profile width derived from white light images and monochromator steps obtained in TV3 provide consistent results also in agreement with estimates derived from direct images. ...

TiTanTM ION PUMPS TiTanTM ION PUMPS TiTanTM ION PUMPS Ion pumps are used in a wide variet y of high and ultra - high vacuum (UHV) environments. ... Gamma Vacuum maintains stock of the most common confi gurations for same - day deliver y. These pumps have the added advantage that they can be mounted in any o r i e n t a t i o n w i t h o u t a d d i t i o n a l s u p p o r t. LOW PROFILE ION PUMPS (100L - 1200L X) Low Profile ion pumps are under 12 in. (300 mm) high for standard confi gurations. ...

We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
