The modules stops if the convergence, i.e. the absolute sum of all corrections over the total number of parameters, is smaller than the configured value.
### Parameters
*`exclude_dut` : Exclude the DUT from the alignment procedure. Default value
is `false`.
*`number_of_tracks`: Number of tracks used in the alignment method chosen. Default value is `20000`.
*`iterations`: Number of times the chosen alignment method is to be iterated. Default value is `3`.
*`dofs`: Degrees of freedom to be aligned. This parameter should be given as vector of six boolean values for the parameters "Translation X", "Translation Y", "Translation Z", "Rotation X", "Rotation Y" and "Rotation Z". The default setting is an alignment of all parameters except for "Translation Z", i.e. `dofs = true, true, false, true, true, true`.

This module measures the efficiency of the device under test by comparing its cluster positions with the interpolated track position at the DUT.
### Parameters
*`pixel_tolerance`: Parameter to discard tracks, which are extrapolated to
the edge of the DUT. Defaults to `1.`, which excludes column/row zero and max.
*`time_cut_frameedge`: Parameter to discard telescope tracks at the frame edges (start and end of the current event window). Defaults to `20ns`.
*`chi2ndof_cut`: Acceptance criterion for telescope tracks, defaults to a value of `3`.
*`inpixel_bin_size`: Parameter to set the bin size of the in-pixel 2D efficiency histogram. This should be given in units of distance and the same value is used in both axes. Defaults to `1.0um`.
