SCULIB_ADDARE - add one real array to another into a third

Description:

Adds two real arrays. Note that any of the arrays may be the same.

Invocation:

CALL SCULIB_ADDARE (N, ARRAY1, ARRAY2, ARRAY3, Q1DATA, Q2DATA, Q3DATA, V1DATA, V2DATA, V3DATA, QUALITY, FLAGGED, VARIANCE)

Arguments:

N = INTEGER (Given)

Number of elements in each array

ARRAY1 (N) = REAL (Given)

Input array

ARRAY2 (N) = REAL (Given)

Second input array

ARRAY3 (N) = REAL (Returned)

Result array. ARRAY3 = ARRAY1 $+$ ARRAY2

Q1DATA (N) = INTEGER (Given)

Quality array for first input array

Q2DATA (N) = INTEGER (Given)

Quality array for second input array

Q3DATA (N) = INTEGER (Returned)

Quality array for output array

V1DATA (N) = REAL (Given)

Variance array for first input array

V2DATA (N) = REAL (Given)

Variance array for second input array

V3DATA (N) = REAL (Returned)

Variance array for output array

QUALITY = LOGICAL (Given)

True if input has quality information

FLAGGED = LOGICAL (Given)

True if input has flagged data values

VARIANCE = LOGICAL (Given)

True if both input arrays have variance arrays

Notes:

• Does not use Quality correctly. Uses INTEGER quality rather than UBYTE
