1. Description
... The motivation for this task is to create one high resolution response matrix for a set of observations without the need for creating individual high resolution matrices. ... This task creates a single response matrix file using information from a list of spectrum from multiple observations, and can also combine spectra and background spectra of the same instrument and spectral order to produce final files that can be used for futher, quantitative analysis in a fitting package such as Xspec. ...

2. HDF-S Flanking Fields Data Reduction / Technical Issues
... The analysis and reduction of the STIS flanking fields proceeded in similar fashion as for the imaging of the Main STIS Field. ... The DARK calibration reference file used in the CALSTIS data reduction steps was constructed using a 'delta-dark' image appropriate for the epoch of the flanking field observations. ... DRIZZLE drop-size used for the flanking fields was a "pixfrac" of 0.8. ... For information on the data reduction, please read first the technical information for the Main WFPC2 Field . ...

6. Indexing and Searching Distributed Astronomical Data Archives
... The technology needed to implement a Distributed Astronomical Data Archive (DADA) is available today (e.g., Fullton 1993). Query interface standards are needed, however, before the DADA information will be discoverable. ... These parameters would be used to index each dataset in each catalog. ... The technology is available today to perform cross-catalog queries, to fetch the data at the click of a mouse, quickly to add new observation catalogs, and to distribute the load across multiple machines. ...

14. Long description of example illustrating background calculation
. This diagram shows a small table with three transparent cells and illustrates how their final background is determined. The table consists of two rows. Four (labeled) cells lie in the first row, but the second cell spans the first and second row. The first, third, and fourth cells of the second row are "empty". Each non-empty cell has a red background and a double black border. Each empty cell has the table's background color (specified as #ff0) as its own. Return to image.

16. Extragalactic Gravitational Wave Background
Next: Gravitational Wave Background from Previous: Galactic Gravitational Wave Background . ... It is intuitively clear that at frequencies above the critical ones for our Galaxy, one will detect rare bright jerks produced by coalescing white dwarfs (at a rate of 1 per 100 year) and NS (at a rate of 1 per - year) in our Galaxy, against a background of the extragalactic stochastic GW. ... Firstly we consider GWB from close individual galaxies, and then will discuss overall extragalactic GWB. ...
