We begin by discussing the CF plane, and then present an argument for re-parameterizing this plane in terms of two frequency indices, leading to what we will be calling ``frequency-frequency'' (FF) analysis. ... Computing the CF plane of a signal, s ( t ), is equivalent to correlating the signal with a family of chirps that are parameterized by chirprate, c and center frequency, . ... Figure 7 . ...

... Abstract: We present the first data release from the second epoch Molonglo Galactic Plane Survey (MGPS-2). MGPS-2 was carried out with the Molonglo Observatory Synthesis Telescope at a frequency of 843 MHz and with a restoring beam of 45 arcsec x 45 arcsec cosec(dec), making it the highest resolution large scale radio survey of the southern Galactic plane. It covers the range |b| 10 deg). In this paper we present the MGPS-2 compact source catalogue. ...
