13.6 Signal correction reset interval  


Description Parameter:	 section 4.3.3
Processing Level:	 SPD
Usage in processing:	 section 7.3.1
File Type:		 Binary FITS Table
File Names:		 PP1RESETI, PP2RESETI, PP3RESETI,
		 	 PC1RESETI, PC2RESETI
In Derive_SPD, each signal is transformed to the equivalent signal for a reference reset interval of 1/4 seconds. The Cal G files provide the correction parameters A0 and A1 as defined in section 7.3.1.

  
13.6.1 Product PP1RESETI: parameters for conversion to 1/4s reset interval for P1

Binary FITS table with record length 24. The record fields are:

Field		Offset	   Number	Type	Description
PP1RESRI 	0	   1 		I*4	Reset interval, n, with tRI=27-n s
PP1RESDR 	4	   1 		I*4	Data reduction factor
PP1RESA0 	4	   1 		R*4	Offset correction, A0 (V/s)
PP1RESA1 	4	   1 		R*4	Slope correction, A1
PP1RESE0 	4	   1 		R*4	Error(standard deviation) in A0 (V/s)
PP1RESE1 	4	   1 		R*4	Error(standard deviation) in A1
