What’s new ?

• New Operators for coordinate conversions:
  – CartesianEquatorial2GalacticOperator
  – CartesianGalactic2EquatorialOperator
  – CartesianEquatorial2HorizontalOperator
  – CartesianHorizontal2EquatorialOperator
  – SphericalEquatorial2GalacticOperator
  – SphericalGalactic2EquatorialOperator
  – SphericalEquatorial2HorizontalOperator
  – SphericalHorizontal2EquatorialOperator
• New interface to healpy, with operators:
  – Healpix2CartesianOperator
  – Cartesian2HealpixOperator
  – Healpix2SphericalOperator
  – Spherical2HealpixOperator
  – HealpixConvolutionGaussianOperator
• New sparse storages:
  – fsc (fixed size sparse column)
  – fsr (fixed size sparse row)
  – fsc_rotation3d (fsc for polarized data)
  – fsr_rotation3d (fsr for polarized data)
• Implement ProjectionOperator (as a SparseOperator subclass), using sparse matrix types FSRMatrix and FSRRotation3dMatrix. This class will supersede ProjectionInMemoryOperator and ProjectionOnFlyOperator. Implemented methods are:
  – canonical_basis_in_kernel
  – restrict
  – pT1
  – pTx_pT1
• In Layout
  – allow unpacked special attributes to be set
  – expose attribute spacing, layout_center, layout_angle, layout_xreflection, layout_yreflection
  – remove autoscale keyword in plot method. Make sure transform has no side effects
• Make Pointing a general purpose class. Add PointingEquatorial, PointingScanEquatorial and PointingHorizontal

Under the hood:

• Make MADmap1 a package inside directory interfaces
• Lazy loading of interface modules
• In Layout
  – use vertices to compute centers
  – enforce attribute ‘removed’ to be an array of the layout’s shape
• Make PySimulators compatible with gfortran 4.5
