... Here we discuss our survey methods, identification procedure and first results. Our survey is found to be efficient at finding flat-spectrum radio-loud quasars (FSRQs, 59 of our first 85 IDs) and BL Lacertae objects (22 of our first 85 IDs), a figure which is comparable to or greater than that achieved by other radio and X-ray survey techniques. ... Particularly important is the identification of a large population of FSRQs ( of DXRBS FSRQs) with ratios of X-ray to radio luminosity . ... FSRQs . ...

... Meta Index / Home Page / Description / How to use Slew data is particularly susceptible to problems caused by background flares, low-energy noise and halos around bright sources. For a practical guide of the issues to be aware of when interpreting slew data please see Saxton et al. ... In this image, problems due to low-energy noise and optical loading can readily be seen. It is worth checking this image for problems before interpreting interesting features in the scientific images. ...
