SLA_XY2XY

Apply Linear Model to an $\left[x,y\right]$

ACTION:

Transform one $\left[x,y\right]$ into another using a linear model of the type produced by the sla_FITXY routine.

CALL:

CALL sla_XY2XY (X1, Y1, COEFFS, X2, Y2)

GIVEN:

RETURNED:

NOTES:

(1)

The model relates two sets of $\left[x,y\right]$ coordinates as follows. Naming the six elements of COEFFS $a,b,c,d,e$ & $f$, the present routine performs the transformation:

$x_2=a+b{x}_1+c{y}_1$
$y_2=d+e{x}_1+f{y}_1$
