SURFLIB_REM_GRID - Remove an image grid of data from demodulated data

Description:

Removes a gridded image from demodulated data using a lookup table containing the (I,J) coordinates (in the grid) of each input data point. Can be used to remove the source from an input data set.

Invocation:

CALL SURFLIB_REM_GRID( N_POS, N_BOLS, NX, NY, IJ, GRID, IN_DATA, STATUS)

Arguments:

N_PTS = INTEGER (Given)

Number of data points in input data

NX = INTEGER (Given)

X dimension of input grid

NY = INTEGER (Given)

Y dimension of input grid

IJ (2, N_PTS) INTEGER (Given)

Positions of each point (I,J) in input grid

GRID ( NX, NY) = REAL (Given)

Image grid to be subtracted from data

IN_DATA( N_PTS ) = REAL (Given & Returned)

Input data to be modified

STATUS = INTEGER (Given & Returned)

Global Status
