This document describes the contents of the Calibration Parameter File (CPF)
generated by the Image Assessment System (IAS) for the Operational Land Imager
(OLI) and the Thermal Infrared Sensor (TIRS). The IAS periodically updates the CPF.
This file is stamped with applicability dates and is published, allowing systems or
individuals who require the file to access it. The CPF is also available to International
Ground Stations (IGSs) and customers via the Landsat Mission Web Site (LMWS). The
CPF supplies the radiometric and geometric correction parameters and other pertinent
parameters required during Level 0 (L0) and Level 1 (L1) processing to create products
of uniform consistency.
This document also describes the Response Linearization Look Up Table (RLUT). The
values contained in the table are a product of the Non-Linear Response
Characterization used to correct the non-linear relationship between the input signal and
the Digital Number (DN) value at the output of the OLI and TIRS instruments.
