Current PCSS Functionalities (I)• Quick-Look Analysis QLA: monitoring of signals in Photometer and

Spectrometer pixels– Offline on stored telemetry or decompressed data

• Preparation of detector selection tables for uplink via GUI Inspect Telemetry and Telecommand Packets:

– Automatically propagated from the MIB definitions– Overview of types, number of packets and parameters in the packet sequence– Selection on type, header fields and any telemetry measure in the packets– Extraction of telemetry measures into Tables for convenient plotting, trend

analysis, operations, save/restore, export

• Decompression of science data – Telemetry Packets to Data Frames

• reduced signals, DMC headers and selected raw data

– Access to signals, samples and DMC headers as Tables and Measures for plotting, visualization, fitting, etc…

• Import of component level CRE/photoconductor data into same structures

– of Tables (automatic labeling, inc. units) and on some primitive arrays – Labels, zooming, hardcopy, plotsymbols, ...

PACS ICC 14

PACS IHDR MPE, 12/13 Nov 2003

Current PCSS Functionalities (II)• Inspection of raw and reduced detector signals

– Statistics on datasets (max, min, mean, median, RMS, sum, ….)– Polynomial fitting on datasets (e.g. integration ramps)– Some functions (FFT, Convolutions)

• Plotting– of Tables (automatic labeling, inc. units) and on some primitive

arrays • Labels, zooming, hardcopy, plotsymbols, ...

• Store the History of your session, edit it and rerun it• Write your own data reduction scripts in jython

– starting from templates and examples

• Define Tables or other data structures to hold intermediate results or CAP results (Calfiles), populate them, save/restore as fits, exchange them

• Export any dataset to FITS

different instrument models / configurations• Improved User Documentation• Optimization for Decompression• IDL Bridge implementation• Intensive User <-> developer ‘workshops’ with immediate implementations of missing

functionalities • IA Processes as plug ins into QLA : BG Subtraction, Averaging, …• TC to TM verification framework• Version control for Detector Selection Tables
