MEMORANDUM TO: Users of Copernicus data
FROM: D. York and A. Miller
SUBJECT: Background in Copernicus Data Tubes


I. INTRODUCTION

For some period of time we have had underway an extensive programming and data reduction effort with the goal of producing background predictions for use in correcting Copernicus data. In this memo we describe the present state of this work.

This report discusses the data reduction procedures ( II); the results, including typical background count behavior for the six tubes ( III); and the possible sources of the background counts in light of the characteristics of the individual tubes ( IV).
