CDIV

Divides an NDF by a scalar

This application divides each pixel of an NDF by a scalar (constant) value to produce a new NDF.

cdiv in scalar out

Input NDF structure whose pixels are to be divided by a scalar.

Output NDF structure.

The value by which the NDF’s pixels are to be divided.

A title for the output NDF. A null value will cause the title of the NDF supplied for Parameter IN to be used instead. [!]

cdiv a 100.0 b

Divides all the pixels in the NDF called a by the constant value 100.0 to produce a new NDF called b.

cdiv in=data1 out=data2 scalar=-38

Divides all the pixels in the NDF called data1 by

-

38 to give data2.

This routine correctly processes the AXIS, DATA, QUALITY, LABEL, TITLE, UNITS, HISTORY, WCS, and VARIANCE components of an NDF data structure and propagates all extensions.
Processing of bad pixels and automatic quality masking are supported.
All non-complex numeric data types can be handled. Arithmetic is carried out using the appropriate floating-point type, but the numeric type of the input pixels is preserved in the output NDF.
Huge NDFs are supported.
