hitfit::EtaDepResolution Class Reference

Hold on to $\eta$-dependent resolution. This class acts as a function object and returns Vector_Resolution as a function of $\eta$. It does not assume symmetry between $+\eta$ and $-\eta$. The interpretation of $\eta$ as physics $\eta$ or detector $\eta$ is left to users's implementation. More...

Detailed Description

Hold on to $\eta$-dependent resolution. This class acts as a function object and returns Vector_Resolution as a function of $\eta$. It does not assume symmetry between $+\eta$ and $-\eta$. The interpretation of $\eta$ as physics $\eta$ or detector $\eta$ is left to users's implementation.

Usage:
Users should write the $\eta$-dependent resolution in a plain ASCII text file with the following format:

etadep_etaminX = etamin

etadep_etamaxX = etamax

etadep_vecresX = vecres

where:

X is an integer starting from 0 (0, 1, 2, 3, ...). Users can write as many resolutions as long as each of them has different integer, and complete information regarding $\eta$ range an resolution.

etamin is a floating-point number, the lower limit of the valid $\eta$ range.

etamax is a floating-point number, the upper limit of the valid $\eta$ range.

vecres is a string-encoded Vector_Resolution, see the documentation for Vector_Resolution class for details.

The constructor will read the ASCII text file and read all resolutions in the file. Then it will instantiate the EtaDepResolution and sort the internal list of EtaDepResElement.
