Organisation of the WWW index pages for each field

For each field the following WWW pages exist (provided the relevant data is available)

• Field index page (created by MK_FIELD_INDEX.PHP). Contains links to WFC quality control plots index and index pages for each XMM source list
• WFC quality control plots index pages (created by MK_WFC_INDEX.PHP) with links to colour-colour plots, differential magnitude, ellipticity and position angle histograms and spatial distribution plots
• Index page for each XMM source list (created by MK_HTML_INDEX.PHP) with links to the XMM/WFC/CIRSI and XMM/APM matching table and a number of plots involving XMM and other data. This includes colour-colour plots of WFC and APM data where the objects with identifications in the X-ray bands are highlighted, as well as likelihood ratio histograms
