Specifications
The correlation between published specifications and performance is unreliable. A
list of numbers reveals virtually nothing. All technical measurements must be sub-
ject to qualitative as well as quantitative interpretation.
Measurements of the DAP yield excellent results by any standards. However, only
those specifications that apply to its actual operation are included here.
