Suggestion for secondary network auxiliary parameters:
BASELxxx We suggest to use the first 5 characters of the NAD83 identifiers
AERODxxx and to add to them the first 3 letters of the province's name.
MCRWVxxx For example:BASELONT for baselines located in Ontario.
LIGHTxxx
MISCxxxx
MEKOMxxx
Note: Provincial agencies are free to submit as many auxiliary parameters as they wish but it is preferable to keep that number small for adjustment convenience. Too many parameters may become confusing to analyize. On the other hand you may want to test certain combinations of values.
