Table 2
Upper and lower bounds on the SRB flux density. The upper bound is built from a cubic spline of maximum SRB observations. The lower bound is built from equation (2). The magnitudes of SRBs estimated to cause disruption for various instruments are listed alongside the instruments in the table.
