Implementation Specification Section number: [General]
In general, this is completely consistent with the displacement models implemented in Trimble software so Trimble supports the adoption of this candidate Specification Topic.
Criticality: [Major]
Requirement: [General]
Implementation Specification Section number: [6.2 Time functions]
Base time function types listed in in table 2 under time function reference formulae make provision for a logarithmic time function but only the natural log ln is listed. However, the deformation model associated with the POSGAR-2007 datum from Argentina uses the log base 10 in their model of post-seismic deformation associated with the 27 Feb 2010 8.8 earthquake in Chile. For this reason, we request that the log base 10 case is also supported in table 2.
Criticality: [Minor]
Comments/justifications for changes: This change is required so that the deformation model that has been adopted by a major South American country will be compliant with the Specification Topic.
