    In the course of our 870um APEX/LABOCA follow up of the Herschel Lensing Survey we have detected a source in AS1063 (RXC J2248.7-4431), that has no counterparts in any of the Herschel PACS/SPIRE bands, it is a Herschel ...

  • Extracting Source Parameters from Gaussian Fits to Two-Particle Correlations 

    Chapman, Scott; Nix, J. Rayford; Heinz, Ulrich (1995-11/19)
    Using a quadratic saddle-point approximation, we show how information about a particle-emitting source can be extracted from gaussian fits to two-particle correlation data. Although the formalism is completely general, ...
