7. FITS IMAGES

The FITS copies of the images in this Atlas are publicly available individually through the NED image server at /forms/images.html and as a collection through a dedicated web page at /level5/Sept02/Palco_BCD/. The FITS headers of these images include, in a homogeneous and self-explanatory way, all the information regarding the image WCS solution and flux calibration along with the date of observation, telescope, filter, exposure time, etc (see the detailed description of the FITS headers of the continuum and Halpha images; see also Table 3). A CDROM with the complete set of FITS images may also be requested from the first author.
