The Wideband Arecibo Pulsar Processor - SNAP Page . SNAP is an application that can process raw WAPP files. ... Both modes (SNAP and WAPP) process data in blocks of 2048 records. ... The plot window presents the WAPP data as different types of XY plots. ... The slider is used to select records in several display modes. ... The reference band is computed by simply averaging all 2048 data records. ... The plot window presents the WAPP data as different types of color intesity waterfalls. ...

These include the tasks used in the STScI pipeline, tools to generate the reference files used by the calibration pipeline tasks, and general image analysis, manipulation, and arithmetic tasks. ... Calnica is used to apply instrumental calibrations to individual datasets, while calnicb is used to process associated sets of NICMOS images. ...

... We have developed a suite of analysis tools and an on-line database for both the primary ChaMPlane X-ray data (source catalogs) as well as the optical counterpart data. ... The ChaMPlane VO provides access to our deep Mosaic optical (V,R,I,Halpha) images, catalogs of their optical photometry, Chandra images with exposure-map correction, X-ray source data and details of X-ray sources with identified optical counterparts. ... Chandra sources are displayed (right) in a smoothed Chandra X-ray . ...

SN 1989B Light Curve Analysis. ... In the light curve depicting their observations, definite trends are noted, here is a "thumb-nail" analysis of the the magnitude estimations of the bright SN (1989B) in the galaxy NGC 3627 (M66). ... The observations were inserted against the V magnitude templete of BL, CCD photometric data, (Wells et. al, (1994) and a color trend (B-V) histogram of the mean type Ia SN (BL)(nutemp.gif). Key Words: Amateur Observations, Supernova, Magnitude Estimates, 1989B . ...

... This task displays an RGS Spectroscopy spatial-dispersion plot (displaying photon position in beta space) and an energy-dispersion plot (displaying photon energy against beta angle in the dispersion direction) created from an RGS event list by evselect . ... Details of the observation are also displayed in each plot. ... The plots may be displayed in monotone or using a number of colour tables (e.g grey-scale, rainbow, heat), and any valid PGPLOT graphics device may be specified for the output. ...
