New analysis tools for the IMGC-02 absolute gravimeter: the linear model implemented via two new programs based on C++/ROOT and R softwares

For the modern Rise-and-Fall Absolute Gravimeters a linear model can be enabled for the processing of the trajectory described by the test body during its motion in the vacuum. Such model presents many advantages and can increase the reliability of the nal measurement. The linear model was applied to the data taken by the INRiM IMGC-02 AG and the results were compared with the ones obtained with the non-linear one. To implement the new model, two dedicated software tools were created. The rst one is written in C++ language and it exploits the ROOT analysis framework. The second one is created using R analysis program. Both programs are described in detail together with the correction evaluations and the data rejection criteria. The whole code is also reported in appendix.
