Package reflectometry :: Package reduction :: Module data :: Class PolarizedData

Class PolarizedData

Polarized data object. This holds all four cross sections of a polarized measurement, and provides operations for aligning and transforming the cross sections.

Instance Methods

__init__(self, **kw)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

source code

set(self, **kw)
Set a number of attributes simultaneously

source code

__str__(self)
str(x)

source code

ispolarized(self)
Indicates that the data is polarized data.

source code

isaligned(self)
Test if all four cross sections have the same Q values.

source code

log(self, msg)
Record corrections that have been applied to the data

source code

spin_asymmetry(self)
Return the spin asymmetry for the pp and mm crosssections.
