### DIV

Divides one NDF data structure by another

#### Description:

The routine divides one NDF  data structure by another pixel-by-pixel to produce a new NDF.

div in1 in2 out

#### Parameters:

First NDF, to be divided by the second NDF.
Second NDF, to be divided into the first NDF.
##### OUT = NDF (Write)
Output NDF to contain the ratio of the two input NDFs.
The title for the output NDF. A null value will cause the title of the NDF supplied for Parameter IN1 to be used instead. [!]

#### Examples:

div a b c
This divides the NDF called a by the NDF called b, to make the NDF called c. NDF c inherits its title from a.
div out=c in1=a in2=b title="Normalised data"
This divides the NDF called a by the NDF called b, to make the NDF called c. NDF c has the title "Normalised data".

#### Notes:

If the two input NDFs have different pixel-index bounds, then they will be trimmed to match before being divided. An error will result if they have no pixels in common.
