FUSE Search Output Columns

This document defines the catalog entries describing the FUSE Data Archive.

Clicking on this box will mark the entry for retrieval.

To Retrieve:
The selected datasets will be downloaded in a single file. You may select the file type: .tar, .tar.gz, .tar.Z, and .zip. After selecting the file type, click on the "Download selected files" button and the selected files will be downloaded to your disk.

To Coplot:
After selecting up to 15 observations to be plotted, click on the "Plot marked spectra" button to coplot the selected observations.

The spectra that you selected will be automatically scaled to the full range of wavelengths and nearly the full range of fluxes (i.e., y axis plot scale runs from 0 (or .25 * the minimum flux for spectra with negative fluxes) to the 10th highest flux). Each spectrum is automatically assigned a color, up to a maximum of 15. The spectra are labelled by their dataset names, with a summary of the datasets plotted given below the plot. After inspecting the plot, you may wish to change the selection of datasets which are displayed. Use your browser "Back" button to do this.

Plot range
Adjust the minimum and maximum wavelengths (in ┼ngstroms) and minimum and maximum fluxes (in erg /cm2/sec/┼) to select the spectral region of interest and to exclude noisy data.

Plot dimensions
Adjust the X size and Y size in pixels to create the size of plot desired. The maximum dimensions ar e 850 by 640 pixels.

Redraw plot
Use this button to replot the spectra when you have changed the plot range or plot dimensions.
