FLUX is the log of the energy per log COMMENT frequency interval, in erg/s. The width of the bandpass and COMMENT the errors on the flux are also given; FREQ1 is the log of the COMMENT frequency of the lower end of the bandpass, FREQ2 the upper COMMENT end. FLUX1 is the (nominally 1 sigma) upper uncertainty in the COMMENT FLUX, i.e. the log of the SED flux is between FLUX+FLUX1 and COMMENT FLUX-FLUX2 (1 sigma). ULFLAG indicates a data point is an COMMENT upper limit. If the SLOPE flag in the OBSTABLE extension is Y, COMMENT the SLOPE, SLOPHI, SLOPLO flags give the best fit power law COMMENT slope within the bandpass and the 1 sigma high and low values.
