RxPec - Visualise periodic error

RxPec is a small utility program that simply reads alignment information from a selected Registax project file and writes a "comma separated values" (.csv) file that MS Excel can use.This makes it very easy to produce a graph showing the periodic error and declination drift in a particular recording processed by Registax.
