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.
