NordicData

Contains information relevant to NordicData header

class NordicData(data=None)

A class that functions as a collection of enums. Contains the information of the phase data line of a nordic file.

Parameters:

data (list) – The data of a nordic phase in a list where each index of a value corresponds to NordicData’s pseudo-enum. The data easily accessed with the enums provided by the class
Variables:
  • station_code (str) – Code of the station. Maximum of 4 characters
