Optical spectra of BL Lac objects
This website reports a database of
optical spectra of ~ 300 BL Lac
objects collected from various literature sources. The targets are listed in an active table yielding this basic information: Name of object with the link to NED, Coordinates (RA, DEC), Redshift or lower limit (when available), and the reference to published papers with the spectra.
For each object a figure and an ascii table of the calibrated spectrum are provided (see example below).
