These spectra were obtained in order to compile a complete sample of quasars for use in a study of quasar evolution. We present a composite optical spectrum made from the subset of 109 quasars that have flux densities in the range 0.25Jy) (2) 24- 30 A7 "MM/YYYY" Date Observation date -------------------------------------------------------------------------------- Note (1): Level of confidence in the redshift 0 = no lines for redshift determination 1 = secure redshift 2 = single line or weak lines Note (2): These classifications are based on both the spectrum and images of the source and their meanings are as follows: Q = confirmed quasar by spectroscopy or UVX photometry BL = spectroscopically-confirmed BL Lac object G = Galaxy with morphological or spectroscopic confirmation NCS = Non-compact radio source (the source is either a steep-spectrum or extended radio source) -------------------------------------------------------------------------------- Byte-by-byte Description of file: notes.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 9 A9 --- Name Name 11- 80 A70 --- Note Text of the note -------------------------------------------------------------------------------- History: From electronic version of the journal ================================================================================ (End) Patricia Bauer [CDS] 11-Feb-2003
