... We present several applications of the AIPS++ environment as applied to the development of the Green Bank Telescope as well as current astrophysical problems. ... In particular, the Green Bank Telescope (GBT) project requires AIPS++ as an analysis environment. To accommodate and facilitate the GBT development, several sets of tools have been fashioned within AIPS++ at several points along the data path, from general calibration routines and data quality assessment to analysis and modeling. ...

Next: A Simple Example With Up: CHIRPLET TRANSFORM SUBSPACES Previous: CHIRPLET TRANSFORM SUBSPACES . 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 . ...
