092 -------------------------------------------

094 For plotting, e.t.c, it is useful to represent the event paramters with a numpy
095 array.
096 The `load_csv` function can be used to load a CSV or CSZ file as numpy array.
097 The `load_eventtxt` function ca be used to load an EVENTTXT file as numpy array.
