SCULIB_CALC_GRID - calculate the minimum rectangular grid that would contain the input jiggle pattern

Description:

This routine takes the x,y coords of the mapped points and attempts to fit them onto a rectangular grid. The grid contains the minimum number of points required to hold the measured positions.

Invocation:

CALL SCULIB_CALC_GRID (N, X, Y, XMIN, XMAX, XSPACE, NX, YMIN, YMAX, YSPACE, NY, IPOS, JPOS, STATUS)

Arguments:

N = INTEGER (Given)

the number of positions in the jiggle pattern

X (N) = REAL (Given)

the x offsets of the jiggle

Y (N) = REAL (Given)

the y offsets

XMIN = REAL (Returned)

the minimum of the output map's x-axis

XMAX = REAL (Returned)

the maximum of the x-axis

XSPACE = REAL (Returned)

the pixel spacing in x

NX = INTEGER (Returned)

the map dimension in x

YMIN = REAL (Returned)

the minimum of the output map's y-axis

YMAX = REAL (Returned)

the maximum of the y-axis

YSPACE = REAL (Returned)

the pixel spacing in y

NY = INTEGER (Returned)

the map dimension in y

IPOS (N) = INTEGER (Returned)

the I index of each jiggle position in the map

JPOS (N) = INTEGER (Returned)

the J index of each jiggle position in the map

STATUS = INTEGER (Given and returned)

global status
