CDIV - Divides an NDF by a scalar

Description:

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

Usage:

cdiv in scalar out

Parameters:

IN = NDF (Read)

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

OUT = NDF (Write)

Output NDF structure.

SCALAR = _DOUBLE (Read)

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

TITLE = LITERAL (Read)

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

Examples:

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.

Implementation Status:

• 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.
