... We employ Bayesian inference for the joint estimation of sources and background on ROSAT All-Sky Survey (RASS) data. ... Background maps were estimated in a single step together with the detection of sources without pixel censoring. ... The source probability is evaluated for single pixels as well as for pixel domains to enhance source detection of weak and extended sources. ... The spline fits the background component whereas count enhancements classify pixel (domains) with source contributions. ...

... Estimation of the residual Soft Proton flare contamination . ... The script can be run on any EPIC event files (MOS1, MOS2 and/or pn), to estimate the amount of *residual* Soft Proton (SP) flare contamination, i.e. it should only be used *after* attempts have been made to clean the event files for SPs using GTI filtering. ... The higher the in-FOV to out-of-FOV ratio, the more the file is contaminated by SPs: . ... File is not contaminated by SPs. ... File is slightly contaminated by SPs. ...

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. ... NICMOSlook and Calnic-C are two programs that were designed to take advantage of the fact that the NICMOS grism mode typically consists of taking both a direct and a grism image. ...

Next: Parameter estimation Up: Basic principles of Previous: Time domain analysis . A simple way to graphically present the results of a TSA is to plot the test statistics S against its parameter or l , depending on whether the analysis was performed in the frequency or time domain. ... Examples of statistics used in the time domain are covariance and correlation functions. The correlation of a signal with itself or with another signal produces maxima in these functions at particular lags. ...

... a major flood of the entire Upper Mississippi River basin which resulted in very wide spread agricultural and commercial damage. On August 10, an enormous plume of turbid river water was detected extending eastward from the Mississippi River delta region. River water discharged on the western side of the delta flowed eastward around the south side of the delta, joining additional river water discharged from passes on the south and east sides of the delta. ...

... Neutral Hydrogen 21cm line emission is widely used to chart the warm and cool diffuse components of the interstellar medium. ... The ongoing Canadian Galactic Plane Survey (CGPS) meets these criteria to an unprecedented degree, permitting the comparison of HI, CO, and dust features at arcminute scales over hundreds of square of degrees of the Milky Way. We will present the first results of an investigation of neutral Hydrogen self-absorption features in the CGPS dataset. ...
