1. Local-background region shapes and sizes
... region (region-7.1.5) [xmmsas_20040318_1831-6.0.0] . ... Local-background regions are in all cases annuli. ... Background regions of this shape should be chosen when there is no extended emission in the FOV, because OA-concentric regions are in general larger than source-concentric ones (thus offer better statisitics), yet sample everywhere approximately the same background level, because the value of the vignetting function is approximately the same at a given radius from the OA. fovbkgannulus =`no...

2. NICMOSlook and Calnic C: Slitless Spectra Extraction Tools
Next: Analysis Tools for Nebular Emission Lines . ... Extracting spectra from a large number of NICMOS grism images requires a convenient interactive tool which allows a user to manipulate direct/grism image pairs. ... The direct image is used to locate objects of interest, to find the position of the appropriate spectra in the grism image, to determine the optimal extraction technique to use, and to calibrate the wavelength range of the extracted spectra. ...

N.B.: The use of imcnts to obtain counts in regions can lead to wrong results when more than one region is used in the same run, if there is any overlap between them, since each pixel can be assigned to ONE AND ONLY ONE region (the last one defined that includes that pixel.

9. Shades and Apparitions: Toward an Inventory of Cold Hydrogen Clouds
With the Phase I CGPS now complete at 21cm, we are in a position to examine the population of cold H I clouds over the entire range of the survey. Current methods of H I self-absorption (HISA) identification and analysis allow us to explore the properties and distribution of the portion of cold H I which appears as HISA shadows in the 21cm line data. Such studies are necessarily biased toward clouds with bright background emission. ...

13. Abstract 218
Butler and Johnston (1994) have reported on the changes in mean air temperature in Northern Ireland over the last 200 years and have found a correlation with solar cycle length, consistent with that reported by Friis-Christensen and Lassen (1991) between solar cycle length and mean Northern hemisphere air temperature. ... As well as data from Northern Ireland, we have used measurements made in Preston, located close to Ireland on the West coast of England. ...

A GRB Host? ... WFPC2 , HST , NASA Explanation: Where do gamma-ray bursts (GRBs) originate? ... But do GRBs occur in galaxies or out alone in deep space? ... It appears to show an extended structure to the lower right of the GRB , which is identified with an arrow. Many astronomers speculate that this extended structure is a distant galaxy , as its colors and subsequent steady emission indicate. Other astronomers worry that the extended emission is variable and so cannot be a galaxy. ...

16. Deforming Plug-plates
... The plug-plates of SDSS project are responsible for locating the optical-fiber plugs spatially and for defining the plug tilt with respect to the surface of best focus. ... Previous attempts to match the SDSS plug-plates to the surface of best focus were conducted using only the bending fixture. The analyses performed indicated that by adding a central constraint to the plug-plate deformation process, the plates could be made to match the surface of best focus within an acceptable range of error. ...
