Abstract
This document reports an analysis of the differences among the REBA parameters optimazion in CSL and in Flight. Such differences arise from 1. presence of a sky signal, in particular the cosmological dipole; 2. different operative conditions; 3. 4K cooler fluctuations; 4. additive constraints to the maximum acceptable processing error which where not considered in CSL. Among the possible additive constrains the most important are: 1. to limit the processing error in total power; 2. to limit the impact of onboard processing on the r deterermination. All of these effects asks to improve the OCA2 optimization procedures in order to have a program adapted to flight conditions. This does not require large modification of OCA2, in most cases it is a matter to add more tests at the output of the application or to use OCA2 in a different manner. However, this could have an impact on the overall speed of the optimization procedure. In the following we will denote with OCA2@CSL the version of OCA2 operated at CSL, and with OCA2@FLIGHT the OCA2 optimizzation algorithm updated for Flight.
