| Summary: | Reorganization of a few pattern-related tables to allow stepping roll angle |
|
SCR 597 | A few columns were moved into the FD_PATTERN table: END_PATTERN, POINT_ORDER and PATTERN_CENTER from DYNAMIC_PATTERN and CYCLE_SIZE from PATTERN_CENTER. The reasons are mostly rather technical (it has to do with the order of applying different pattern features). For the cycle size the reason is that the meaning of this property was the number of pointings after which a shift in pattern center would occur. Now the meaning is a little bit more general as it also is the number of pointings after which the roll angle change occurs. If a pattern has a non-static roll angle strategy but no wandering COP, the cycle size cannot be defined in the PATTERN_CENTER table. |
