cSqrTSensor
This class is just method globber that works expects as input TimeSeries objects defined by pylal.frutils.

Functions

[hide private]

CSTdot(A, B)
Input two matrices Nx3 in size.

source code

CSTcross(A, B)
Input two matrices Nx3 in size.

source code

intersectPlanes(normA, normB, coordA, coordB, wiggleA=0.0)
Expects a 3xM matrices of 3D vectors for the plane norms also in addition to that we take vectors from the "origin" (0,0,0) (single 3x1 matrix) to be the coordinate input.

source code

intersectLines(vecA, vecB, coordA, coordB, wiggleA=0.0)
Expects inputs of 3xM matrices representing vectors along a line and a vector 3xM of matching points on lines for those vectors.

Function Details

[hide private]

CSTdot(A, B)

source code

Input two matrices Nx3 in size. Calculates the inner product row by row.

CSTcross(A, B)

source code

Input two matrices Nx3 in size. Calculates the cross product row by row.

intersectPlanes(normA, normB, coordA, coordB, wiggleA=0.0)

source code

Expects a 3xM matrices of 3D vectors for the plane norms also in addition to that we take vectors from the "origin" (0,0,0) (single 3x1 matrix) to be the coordinate input. The output is a tuple of 3xM arrays parameterized by their index, intersection vector and point on that line. Output is (linePoint,LineVector) ((3xM),(3xM)). The input wiggleA is the wiggle angle in radian to consider two vectors parrallel.

intersectLines(vecA, vecB, coordA, coordB, wiggleA=0.0)

source code

Expects inputs of 3xM matrices representing vectors along a line and a vector 3xM of matching points on lines for those vectors. Output is in a 3xM collection of intersecting points. Examples: Input ([[vX,vY,vZ]],[[lX,lY,lZ]])

Output [[i,j,k]] A set of lines is considered parallel if angle(rads) between then is less than wiggleA, in this case the output coordinate is (NaN,NaN,NaN).
