PN HALOES

NGC 6826 Ha

An image database of

Planetary Nebulae HALOES

NGC 6629 [OIII]

The image database presented in this page contains a collection of deep narrowband images of planetary nebulae (PNe) which formed the base of the following two papers:
Corradi, Schönberner, Steffen & Perinotto (2003 MNRAS 340, 417) (link to ADS), and
Corradi, Sanchez-Blazquez, Mellema, Giammanco, & Schwarz (2004 A&A 417, 637) (link to ADS).

The database contains about two hundred optical narrowband images of planetary nebulae (PNe) obtained at different telescopes as described in the articles, plus about 60 images from the literature and kindly provided by the authors of various articles, as well as an INCREASING number of deep PN images collected after the publications of our papers. The deep images in the database were used to search and study PNe haloes. The definition adopted for the haloes, the description of the observations, notes on individual objects and the discussion of the statistical observational properties of PNe haloes can be found in the papers. The b/w JPEG images in Corradi et al. (2003) are also available here individually, together with some colour PDF/JPEG pictures not published in the papers. All data are summarized in Tables 1 and 2 below, that are an extended version of Tables 1 and 2 in Corradi et al. (2003).

THIS PAGE, WHICH HAS MOVED FROM ITS ORIGINAL SITE, IS NOW UNDER CONSTRUCTIONS, AND SOME OF THE LINKS BELOW, AND SPECIFICALLY THE DOWNLOAD OF THE FITS IMAGES, ARE TEMPORARILY NOT WORKING. PLEASE CONTACT ME IF YOU NEED ANY SPECIFIC FITS IMAGE, AND I WILL PROMPTLY SEND IT TO YOU.

NOTE: Images and pictures can be retrieved provided that the original source is properly referenced in any publication that results from their use. For images of Table 1, a reference to the two papers above (or just the relevant one) should be included. For images in Table 2, please cite the original paper (column "Source") and acknowledge the authors.
