FEB input data format
---------------------

The input data must be provided as follows. Each line refers to a 32-bit word.

Gains		ch.39 ch.38 ... ch.32 | ch.7 ch.6 ... ch.0
ADC sample 0	ch.32 | ch.0
ADC sample 1    ch.32 | ch.0
...
ADC sample 4    ch.39 | ch.7
Gains		ch.47 ch.46 ... ch.40 | ch.15 ch.14 ... ch.8
ADC sample 0	ch.40 | ch.8
ADC sample 1	ch.40 | ch.8
...
ADC sample 4	ch.47 | ch.15
Gains		ch.55 ch.54 ... ch.48 | ch.23 ch.22 ... ch.16
ADC sample 0	ch.48 | ch.16
ADC sample 1	ch.48 | ch.16
...
ADC sample 4	ch.55 | ch.23
Gains		ch.63 ch.62 ... ch.56 | ch.31 ch.30 ... ch.24
ADC sample 0	ch.56 | ch.24
ADC sample 1	ch.56 | ch.24
...
ADC sample 4	ch.63 | ch.31


Output data format
------------------

Calibration constants format
----------------------------

There are 16 32-bit words for each gain and for each channel. These are:

			MSB	LSB
		--------------------
		0	n.a.	n.a.
		1	n.a.	n.a.
		2	n.a.	n.a.
		3	a1	b1
		4	a2	b2
		5	a3	b3
		6	a4	b4
		7	a5	b5
		8	h1	h2
		9	h3	h4
		10	h5	-2p
		11	sum(h)	S_E-n
		12	-p * sum(a)	[32 bits]
		13	-p * sum(b)	[32 bits]
		14	2p * sum(h)	[32 bits]
		15	5p^2		[32 bits]

The blocks are then arranged as follows:

_cc_table:	ch  0,	gain 1
		ch 32,	gain 1
		ch  0,	gain 2
		ch 32,	gain 2
		ch  0,	gain 3
		ch 32,	gain 3
		ch  1,	gain 1
		...
		ch 63,	gain 3
