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

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 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?
