SIToolBox : A package for Bayesian estimation of the isotropy violation
  in the CMB sky
  The standard model of cosmology predicts a statistically isotropic (SI) CMB
sky. However, the SI violation signals are always present in an observed
sky-map. Different cosmological artifacts, measurement effects and unavoidable
effects during data analysis etc. may lead to isotropy violation in an
otherwise SI sky. Therefore, a proper data analysis technique should calculate
all these SI violation signals, so that they can be matched with SI violation
signals from the known sources and then conclude if there is any intrinsic SI
violation in the CMB sky. In one of our recent works, we presented a general
Bayesian formalism for measuring the isotropy violation signals in the CMB sky
in presence of an idealized isotropic noise. In this paper, we have extended
the mechanism and develop a software package, SIToolBox, for measuring SI
violation in presence of anisotropic noise and masking.
