...eq_pol2fit_coeff) [*]
when $\Delta(i)=0$ eqq. [*] cannot be used: in this case, the best parabolic fit coincides with the ``special'' case of the linear fit.

... [*]
Actually, because of the limited size of the variables, the computer CPU deals with, the count and time arrays ought to be rescaled, then used for fitting, and finally rescaled back.

... (GSM)[*]
When the attitude control becomes unstable, the spacecraft starts the GSM, thus stopping any scientific activities, untill the control is restored; this procedure is aimed to prevent from damages.
