Module gwy :: Class PlaneFitQuantity

Class PlaneFitQuantity

Local plane fitting quantity to request from DataField.area_fit_local_planes() and similar functions.

Note: All the enumerated values are defined at the module level, not the class level. The are just groupped by class here for easier orientation.

Class Variables

PLANE_FIT_A
Constant coefficient (mean value).

PLANE_FIT_ANGLE
Slope orientation in (x,y) plane (in radians).

PLANE_FIT_BX
Linear coefficient in x, where x is in pixel coordinates.

PLANE_FIT_BY
Linear coefficient in y, where y is in pixel coordinates.

PLANE_FIT_S0
Residual sum of squares.

PLANE_FIT_S0_REDUCED
Slope-reduced residual sum of squares.

PLANE_FIT_SLOPE
Absolute slope value (that is sqrt(bx*bx + by*by)).
