// ============
//
// Derotate a MCamEvent and fill a histogram with derotated data
// (sky-plot).
//
// As an input you need a merpped root file conataining DC information
// from a camera report file. To be able to derotate you also need
// aproproitate time-stamps and the corresponding pointing information.
//
// All events are filled into a 2D histograms - derotated.
//
// The example shows the usage of MHCamEventRot. The output is the derotated
// sky-plot.
