Control parameters
The control parameters are the param-
eters that control the specific operations
of each of the splicing processes, and
the following tables organizes them
accordingly.
Observe that two of the control param-
eters for Small core alignment, MAX.
ECCENTRICITY and ACCEPTABLE
OFFSET (see next page), have multiple
functions. The figures on the right shows
you how to set these parameters.
For more details on the control , you can
also refer to the preceding section on
splicing processes (p. 28-35).

Note that you will revoke the small core alignment process and invoke the hot core align-
ment process if you set MAX. ECCENTRICITY to a value that is greater than 2.9

you set
ACCEPTABLE OFFSET
to a value that is greater than 0.9
m
m, you will set the PULL-
ING DISTANCE parameter and thereby revoke the pulling procedure.
