Target Acquisitions and Peakups . ... For science observations taken through slits which are smaller than 3 arcseconds in either dimension, and for use of the coronagraphic bars, you will need to specify a target acquisition exposure to center the target in the science aperture. ...

... 295, 2003 H. E. Payne, R. I. Jedrzejewski, and R. N. Hook, eds. The MAST Pointings Tables Pro ject Karen Levay, Paolo Padovani1 , Randall Thompson, Megan Donahue, Michael Corbin Space Telescope Science Institute, 3700 San Martin Drive, Baltimore, MD 21218 Abstract. We have undertaken a pro ject to create a database of all HST imaging observations organized by position on the sky. ... Each sky region was called a "pointing." ... Users select the instrument pointings table they wish to search. ...

... 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. ...

VLT Science Verification Policy and Procedures Version 2.0 - August 2006 Science Verification Observations An integral part of the Commissioning of a new VLT instrument is a series of Science Verification (SV) observations. ... All SV Observations are conducted in Service Mode and usually some members of the SV Team are present at Paranal Observatory for a prompt reduction of the data, and the selection of the observations to be executed. ...

GRANAT is the Russian x-ray sattelite launched to the high apogee orbit (200,000 km) and operated almost for 10 years (1989 -1999) , carrying out four major instruments: French SIGMA coded-mask hard x-ray telescope (30-1000 keV), Soviet ART-P coded-mask telescope (2??-60?? keV), all-sky monitor WATCH (6-150 keV), and a gamma-burst detector PHEBUS . ... Since September 1994, GRANAT is in the survey mode. ... Explore pages devoted to individual GRANAT instruments (including main scientific results): . ...

... The task clearly needs to know the direction in space of the focal axis of the relevant instrument at the time of the observation of interest. There are three necessary pieces of information: the name of the instrument, the date-time of the observation and the spacecraft pointing direction (attitude) at this time. ... There are two ways to pass the `cal' information to esky2det , governed by the parameter calinfostyle : . ...

The original plan called for "Wind" to approach its final station over two years, undergoing two close encounters with the Moon to boost its speed. ... If however the object is moving , the encounter is not symmetric, and in the end the spacecraft may have gained or lost speed, depending on its trajectory. ...

... Ignacio Ugarte Urra's PhD thesis topic is the investigation of coronal bright points. In his first paper (in collaboration with Gerry Doyle and Maria Madjarska) he investigated the formation, evolution and decay of a coronal bright point via a spectroscopic analysis of its transition region counterpart and the evolution of the underlying magnetic bipole during 3 days of almost continuous observations. ... In general the bright point has a radiance 4 times higher than that of the network. ...
