LOG10

Takes the base-10 logarithm of an NDF data structure

Description:

This routine takes the base-10 logarithm of each pixel of a NDF  to produce a new NDF data structure.

This command is a synonym for logar base=10D0.

Usage:

log10 in out

Parameters:

IN = NDF (Read)
Input NDF data structure.
OUT = NDF (Write)
Output NDF data structure being the logarithm of the input NDF.
TITLE = LITERAL (Read)
The title for the output NDF. A null value will cause the title of the NDF supplied for Parameter IN to be used instead. [!]

Examples:

log10 a b
This takes logarithms to base ten of the pixels in the NDF called a, to make the NDF called b. NDF b inherits its title from a.
log10 title="Abell 4321" out=b in=a
This takes logarithms to base ten of the pixels in the NDF called a, to make the NDF called b. NDF b has the title "Abell 4321".
