Some of the parameter constants used throughout the AEZ-CCS package are defined by expressions involving other parameter constants (marked with a ‘C’ in the above table).Their values are given by:
MGRASS = MFCR + MCCR + 1
MCRP = MGRASS + MTREE
MLVS = MLVS1 + MLVS2
MYCR = MYFC + MCCR + 1
MYPR = MYCR + MYLV
MFXROW = MQAG + 2*MYCR + MINPT + 2*MLVZ + MLVS + MINVST + 5
* Parameter constant expression involving other parameter constants.
