Program: SCALE

Purpose: Program to scale the data in subsets by a factor and an
offset.

Category: MANIPULATION, UTILITY

File: scale.shl

Author: K.G. Begeman

Keywords:

INSET= Set (and subset(s)) to scale. Maximum number of input
and output subsets is 2048.

BOX= Frame in subsets to scale [entire subset].

OUTSET= Set and subset(s) where to store the scaled data.
[input set].

** A= Enter scaling factor(s) [1.0]. If you need different
scaling factors for each subset, you should use this
keyword.

** B= Enter offset(s) [0.0]. Only asked if different scaling
factors are wanted.

AB= Give scaling factor and offset [1.0,0.0]. Output
subsets will be: A * input subset + B.

** OPTION= Option which determines what to do with the data outside
BOX [0]. The different options are:
0 Scale inside BOX and set to blank outside BOX.
1 Scale outside BOX and set BOX to blank.
2 Scale BOX and transfer unscaled outside BOX.
3 Scale outside BOX and transfer BOX unscaled.

Example: SCALE
SCALE ,INSET=AURORA FREQ
Set AURORA has 3 axes
RA-NCP from -7 to 8
DEC-NCP from -7 to 8
FREQ-OHEL from 1 to 59
SCALE ,BOX=PC D 8 8
BOX range for set AURORA :
RA-NCP from -3 to 4
DEC-NCP from -3 to 4
SCALE ,OUTSET=
SCALE ,OKAY=
Set AURORA has 3 axes
RA-NCP from -7 to 8
DEC-NCP from -7 to 8
FREQ-OHEL from 1 to 59
SCALE ,AB=1.1 -0.1 OPTION=2
Data inside BOX will be scaled
Data outside BOX will be transferred unscaled
SCALE +++ FINISHED +++

Updates: Jan 31, 1990: KGB Document created.
Dec 11, 1991: KGB Cancel replaced by reject.
Jul 12, 1994: KGB Allow for different scaling factors.
