       The flux was normalized at the nearby continuum bands.

6.    Spectrum (View): Link => FAST spectrum of the object (To see)
       The flux was normalized at 5500 A.
       The detector response was taken out using spectrophotometric standard stars and the IRAF sensfunc task.
       Warning: This procedure is not a flux calibration of the spectrum.

        Observations were done at the 1.5 meter telescope of the Whipple Observatory with the FAST Spectrograph, equipped with the Loral 512 x 2688 CCD (15 microns square pixels).  The spectrograph was set up in the standard configuration used for FAST COMBO projects: the 300 groove mm^{-1} grating and a 3''  wide slit. This combination offers 3400A of spectral coverage centered at 5500A, with a resolution ~ 6A.

       The magnitude (mo) corrected for absorption (mo=m-Am) was calculated using the relations from Cardelli et al (1989) and the Av
       derived from the color excess E(B-V) using different extinction law (Rv=3.1 and Rv=5.0)

       Av=Rv*E(B-V)

        Objects without spectral type in Hernández et al (2003) were plotted using an estimated type, taken from Table 10, column 6, in Hernández et al (2003), previously published spectral types were used for the continuum stars. The nominal error was set as one spectral type. These SED should de used with caution. See Hernández et al (2003) for details.

       The line at the upper panel (V magnitude) show the median value of the data.
        The plot also show the information about the median values of colors U-B, B-Vand V-Rj.
        If are available, we give the median values of Rj-Ij, V-Rc, and  Rc-Ic  at the top of each figure.
      
These data was obtained from Van Vleck Observatory database (Wesleyan University).
