absorber	Calibflt
	Structure to hold coeffs if alternative #2 is chosen.

Detailed Description

Definition of absorber filter. The filter can be defined in 2 alternative ways: 1.- Just like a you define a sample, layer by layer (the transmission being calculated for each relevant line). 2.- Defining its transmission function by giving a series of coefficients that fit T(E) (this was the default way in DATPIXE).
