They will be later replaced by a link to a web page with the same content. The comment field for each measure, if present, contains six fields: - used sequence (OT = Odd Trondall Image, AH = Arne HENDEN sequence) - comparison star(s) - measure method (A = Aperture, G = Gaussian Fit) - FWHM (arcsec) - total exposure (s) - SN elevation (°) For each observer, the description contains 6 fields: - VSNET code - first and last name - location (fr = France) - instrument - CCD type - software used for measures Software SNWeb provided by Jean-Claude PELLE ( jcpelle@mail.pf ) Jean-Marie LLAPASSET Obs 635 Perpignan (France) http://perso.wanadoo.fr/jm.llapasset http://vsnet.astrosurf.com/snweb/
