1. Exchange channels and reduction
Exchange channels cannot be reduced by other channels defined. If one tries, no reduction will be done. However, the user will be left unnotified which is a flaw. This problem will be fixed in the next release.
2. Date of the 1st observation of a record for sampling intervals < 1 hour
In (very seldom) cases, where the sampling interval is less than 1 hours and the first observation does not exhibit a full hour , the minutes and seconds are upward adjusted to a full hour. This will affect the analysed phases of the non-linear and additional harmonics defined in *- nl+adconst.dat by an amount w = angular velocity at maximum .
Also the automatic change of the sampling interval to hourly sampling (parameter CHANGETOHI =1) does not work.
Workaround is to only analyse sampled data where the 1st observation is sampled at full hour. This problem will be fixed in the next release.
3. File *\commdat-v80\nonlinear.dat
The entries for K3 , 4MO7 and S74b have to be changed to:
NL 3 3 3 0 0 0 -3 0 0 0 0 0 45.12320004 0. 0. 0. 0. K3 = 4MK2O3 =TGP close to S3bbb
NL 7 7 1 0 0 0 0 0 0 0 0 0101.99338136 0. 0. 0. 0. 4MO7 = 3MK7
NL 7 7 7 -3 0 0 -4 0 0 0 0 0105.16426672 0. 0. 0. 0. S74b
Also, the frequencies the *.ini files of dimension cpd have to be updated by taking the angular velocities in °/h, listed above , and deviding by 15:
NL+ADCONST= 3.008213 1.000000 .000000 K3 # shallow water tide wave **** TGP 4MK2O3 bbb
NL+ADCONST= 6.799559 1.000000 .000000 4MO7 # shallow water tide wave
NL+ADCONST= 7.010951 1.000000 .000000 S74b # shallow water tide wave 4b
