Main Changes in this Version:

  • The astWrite method of the FitsChan class can now create FITS-WCS headers
    that include keyords describing focal plane distortion using the
    conventions of the Spitzer SIP scheme. This is however only possible if
    the SipOK attribute of the FitsChan is set to a non-zero value (which is
    the default), and the FrameSet being written out contains an appropriate
    PolyMap that conforms to the requirements of the SIP convention.

  • The behaviour of the astLinearApprox method of the Mapping class has
    been changed in cases where the Mapping being approximated generates bad
    (AST__BAD) values for one or more of its outputs. Previously, any such
    Mapping would be deemed non-linear and no fit would be returned. Now, a
    fit is returned, provided the other outputs of the Mapping are linear,
    but the fit contains AST__BAD values for the coefficients describing the
    bad Mapping output.
