Notes. Column 2 lists the wavelength ranges covered by the various instruments and filters used for observations. Note that Swift-UVOT and XMM-OM filters do not cover exactly the same range, despite similar filter names. Column 3 lists the number of targets detected by each observatory which have flux measurements included in the catalogue. UL means targets have an upper limit value available rather than a detection.
