Units Abbreviations Blockette 34 Provide the Units of all fields after transfert function INST-IPGP
Raw channels Dictionary (Acquisition System  Dictionary) Proposal: use a dictionnary for these filters, as they are not expected to be changed and as many of these filters will be used for different channels
SEIS-AC FIR Dictionary Blockette 41 FIR acquisition filter from SEIS AC ( 100 sps, 20 sps, 1 sps and 1/10 sps) SISMOC from FSW
APSS FIR Dictionary Blockette 41 FIR acquisition filter from APSS ( 20 sps) INST-APSS
APSS Decimation Dictionary Blockette 47 Decimation performed by the FPGA, if any INST-APSS
TWINS None IS Twins making a raw acquisition without any FIR or filtering? INST-TWINS
FSW channels Dictionary
FSW FIR Dictionary FIR Dictionary Blockette 41 FIR decimation filters applied to any channel by the FSW SISMOC from FSW
TWINS Decimation Dictionary Blockette 47 Decimation performed by the FSW, if any SISMOC from FSW
FSW channel Disctionnary: FIR Dictionary
FIR Dictionary Blockette 41 List all FIRs of the FSW dictionary SISMOC from FSW
Response (Coefficients) Dictionary Blockette 44 List the coefficient of all FIRS of the FSW Dictionary SISMOC from FSW
Decimation Dictionary Blockette 47 List the decimation of all FIRS of the FSW Dictionary SISMOC from FSW
Channel Sensitivity/Gain Dictionary Blockette 48 List the gain of all FIRs of the FSW Dictionary SISMOC from FSW
Note: The mean of N samples shall be listed here as a FIR
Composite channels other operation Dictionary
VBBZ, SPZ Beam Configuration Blockette 35 Beam formation (i.e. addition with coefficient) from 3 channels SISMOC from FSW
SEISVELZ Beam Configuration Blockette  35 Beam formation (i.e. addition with coefficient) from 6 channels SISMOC from FSW
ESTASP, ESTAVBB, ESTAP, ESTAM Beam configuration Blockette 35 Beam formation from 2 channels ( mean of square MINUS squared mean) SISMOC from FSW
ESTASP, ESTAVBB, ESTAP, ESTAM Response (Polynomial) Dictionary Blockette 42 SISMOC from FSW
Station Control Headers
Station Identifier Blockette 50 Location of the sensors from Mission info SISMOC FROM JPL
Station comment Blockette 51 Include any data outage and times corrections history on weekly basis (when providing validated data). To be defined. Which is the best approach? SISMOC
Channel identifier Blockette 52 Mix stations and FSW informations and Instrument informations (Azimuth and dip of the sensor) SISMOC + INST
Channel Instrument response information
For all Temperature channels Response Polynomial Blockette 62 Polynomial interpolation of the temperature sensor INST-CNES
For all seismic channels of VBB (POSVBB, VBB) Response (Poles and Zeros)  Blockette + Channel Sensitivity /Gain Blockette 53+58 Transfert function of the VBB axis, for all differents configurations. 53 for transfert function and 58 for gain change, assuming the later without impact on the transfer function INST-IPGP
For all seismic channels of SP (POSSP, VELSP) Response (Poles and Zeros)  Blockette + Decimation Blockette + Channel Sensitivity /Gain Blockette 53+57+58 Transfert function of the SP axis, for all differents configurations INST-IC
For all APSS channels related to MAG Response (Poles and Zeros)  Blockette + Decimation Blockette + Channel Sensitivity /Gain Blockette 53+57+58 Transfert function of the MAG axis, for all differents configurations INST-UCLA
For all APSS channels related to the pressure sensor Response (Poles and Zeros)  Blockette + Decimation Blockette + Channel Sensitivity /Gain Blockette 53+57+58 Transfert function of the pressure sensor, for all differents configurations INST-JPL
FOR TWINS Only the Channel sensitivity ? 57+58 A priori no transfert function, as data transmitted to CNES in physical unit.  SISMOC
Note and question:  Poles and Zeros are recommanded. However, the response can be provided also with blockette 55 if only a response function with frequency variable can be provided. Blockette 55 provide also a plot of the transfer function. Shall whe put it?
Flight sofware processing history
For all channels decimated by the flight software or resulting from flight software decimated data  Response Reference Blockette 60 List all stages of the processing from instrument to output of a given channel SISMOC from FSW
Data Records blockettes
For all data Fixed Data header To be populated by SISMOC related or operation related informations on the following events: SISMOC
Calibration in action SISMOC from FSW
Event data request SISMOC
Not used. Saturation detection history will be put in QuakeML SISMOC from auto-SISMOC
Not used. Spike detection history will be put in QuakeML SISMOC from auto-SISMOC
Not used. Glitches detection history will be put in QuakeML SISMOC from auto-SISMOC
Not used. Block is stop and restart when a data is missing. SISMOC
Not used. Transmission error are assumed to  be small. SISMOC
Generaly not used, as only event data can have this status of digital filter charging SISMOC from FSW
