Test data set for the cumulative transformation parameters
==========================================================
Only valid for transformations with parameters for 2023-03-01 to 2024-02-29
(See file: RSN2023CUM_I20.CSV)

*** Example ***
Epoch of Observation: 22.02.2023 = Day 53 of 365 = 2023+(53/365)
    = Fraction of the year (tc): 2023.15
Reference Epoch(t0): 2021.0 ==> tc - t0 = 2.15
