1. Description
... rgsspectrum creates an OGIP-compliant spectrum of counts for a single RGS exposure. ... background-corrected source spectrum . ... Note that although the spatial selection region for the background spectrum is not source-specific, the energy selection region is source-specific, and for this reason the background spectrum is technically source-specific. ... The above description of the BACKSCAL column applies only to Spectroscopy mode data; in HTR mode this column has nothing to do with exposure. ...

3. Long description for background pattern
. This diagram illustrates how a background image may be repeated within the content and padding areas of a box. In this example, a background image is first centered within a box (established by the BODY element of the example). The box contains paragraphs of text, shown in gray to make them discrete. The image, a blue wavy line on a pale yellow background, is then repeated vertically, to the top and bottom of the BODY box. The effect is to create a wavy band down the center of the page. Return to image.

4. A Brief Description of the Instrument and Its Operation
... The GHRS has the usual components of an astronomical spectrograph: entrance apertures, a collimator, dispersers, camera mirrors, and detectors. ... The collimator and camera mirrors are unexceptional and need no further description here (see ``The HST Focal Plane and the GHRS Apertures'' on page 73 for details). ... The first two first-order gratings, G140L and G140M, have their spectra imaged by mirror Cam-A onto detector D1, which is optimized for the shortest wavelengths. ...

5. MILT Description
... This is possible at modest cost due to the low moments of inertia of the telescope and enclosure. ... This same performance will be achieved in higher winds when the telescope enclosure is facing away from the wind, or by using wind screens. ... The telescope system (MILT) will be remotely operable with an on-site operator's assistance by an astronomer located at one of the ARC member institutions. ... Mean Wind Speed . ... Offsets > 10 deg: 1 arc sec rms max . ... 5 sec max, tracking to tracking . ...

7. The High-Z SN Search Description
The Doppler shift is the effect of sound increasing or decreasing in pitch as an object moves towards or away from you. ... Light works the same way, except light is shifted to redder colours when an object is moving away, and to blue colours when an object is travelling towards us. ... Almost every object he observed had its light stretched to redder colours, indicating essentially everything in the Universe was moving away from us. ... So the Hubble constant tells us how old the Universe is. ...
