        mmy,
        p,
        )

Make diffracted ray from mmx, mmy and goniometer position. This can be called either with float or with Numeric.array versions of mmx and mmy

        )

Make ideal vector (on detector with ideal position and alignment) from mmx,mmy and goniometer position.

newalign ( self )

Calculates a new detector alignment matrix and its inverse. Must be called whenever the detector alignment rotations are modified.

pix2mm (

Get mm coordinates from pixel values. This can be called with float values pixv and pixh, or with complete Numeric arrays of data. In the former case, a distortion.error exception will be raised if the pixel coordinates are far outside of the detector, where the distortion polynomial does no longer hold.
