摘要：

In Bischof et al. (this conference) a novel on-board data reduction concept for FIRST/PACS is proposed, consisting of following modules: ramp fitting, integration, glitch detection and spatial/temporal redundancy reduction. In this paper we outline the experiments of the data reduction software on synthetic and astronomical data. These experiments demonstrate the feasibility of this novel approach. The evaluation of its core modules on observational data from ISO is presented. We mainly focus on the performances of the ramp fitting and the glitch detection modules.
