sarkit.crsd.interpolate_support_array

interpolate_support_array(x, y, x_0, y_0, x_ss, y_ss, sa, dv_sa=None)

Method for computing values from a support array as in 9.3.2

The method in 9.3.2 is specified for a support array containing two parameters. This function only handles a single parameter.

Due to its reuse in 7.5.3, some variables have been renamed/generalized:

• dcx, dcx -> x, y

• {Gsa, PhiSA} -> sa

• {NumRows, NumCols} -> sa.shape

• {G, Phi} -> values

Parameters:

x, yarray_like

Row and column values in support array coordinates at which to interpolate. Must have the same shape.

x_0, y_0float

Row and column 0 coordinate

x_ss, y_ssfloat

Row and column coordinate sample spacing

saarray_like

2-D support array to interpolate

dv_saarray_like or None, optional

Data valid array of the same shape as the support array. If None, the entire support array is treated as valid.

Returns:

valuesndarray

Computed array values at (x, y)

dvndarray

Data valid array, where True indicates that values contains a valid value
