This task in the aXe package takes the input catalog and the aXe output files and produces an html summary. The core of that summary are object pages that display a number of results for each catalogue object in an html table. Every object is displayed as a table row, giving the reference number, magnitude in the magnitude system of the direct object, the X and Y position of the direct object, its Right Ascension and Declination, a cut-out image showing the direct object, the spectral stamp image showing the 2D spectrum, a 1D extracted spectrum in counts and the same in calibrated flux units.

To facilitate the navigation within a data set, overview and index pages accompany the object pages. The overview page contains for each object the basic information sequence number, reference number, X,Y,RA,Dec and magnitude. The index page includes a table with the ordered reference number of all objects. Direct links from both the overview page and the index page take you to the corresponding locations of the objects in the object pages. An overview of aXe2web is given in Walsh & Kümmel (2004).

The details of the html summary produced by aXe2web are controlled by a set of about 20 keywords or settings, which influence the presentation of the objects in various ways. There exist, for example, keywords/settings to

A detailed list of all settings can be found by following the links given in section Documentation. To download and install aXe2web, please go to here.

Examples of an html summary created by aXe2web are given here:

In both examples the flagging of contaminated data points with blue symbols alerts the viewer to consider these pixels with caution.

aXe2web-1.3 release notes

aXe2Web version 1.3 contains only 1 update to the code, which was to have the automatic scaling that is applied to 2D images displayed on the output web pages ignore bad pixels, so that the intensity display range is not thrown off by bad values. This change was made in the prepare_data method.

aXe2web-1.2 release notes

aXe2web version 1.2 introduced NO new features. Many internal workings of the program have been updated, especially with regard to the packages on which it depends. The spectral plots and the direct image stamps are now produced with matplotlib. The version 1.2 requires only the python modules pyfits, PyRAF/IRAF, numpy and matplotlib, which are fairly common in the astronomy community and are all available e.g. in the Scisoft collection.
