NULL value in IDL ? [message #42324] Tue, 01 February 2005 11:11

Hello,
Is there in IDL a way to give a variable the value NULL, meaning 'no data' ?
My problem is that I use REBIN() to reduce an image, but some parts of
this image do not contain information, even is the value is zero. These
zero-value pixels are hence taken into account in the REBIN()
calculation, and that's what I would like to avoid.

Thanks for any help,

Jerome
