Resolve issue with MS4 nodal factor
requested to merge extdevs/nemo:583_MS4_nodal_factor into 583-review-of-the-tidal-constituent-parameters
I originally thought that the MS4 nodal factor was wrong and should follow S58. Communicating with AVISO-FES (who had defined it differently) I learnt about the error in S58, which is corrected in Pugh87.
Summary: . S58 nodal factor for MS4 is incorrect. . Pugh87 justifies the correct choice. I have added the Pugh citation and explanation.
Also:
- citation edits: S54 --> S58
- Parameter sources: The Overtides should include "Table 2a" in the penultimate column, if from Schureman
