I have two questions about "dynamic land use" files of clm and I hope soneone can help me.1  What is the unit of "harvest from primary forest" in this file? (most values of this variable are less than 0.006)2  In this file, pft dimension is 17, however, in the Technical Description for CLM4.5, only 15 different PTFs are defined, so I wonder details about these 17 different PTFs.Thank you for your help!

I think that the units are:       ! If this is a tree pft, then      ! get the annual harvest "mortality" rate (am) from harvest array      ! and convert to rate per second      if (ivt(p) > noveg .and. ivt(p) < nbrdlf_evr_shrub) then          if (do_harvest) then            am = harvest(g)            m  = am/(days_per_year * secspday)         else            m = 0._r8         end if so, fraction per year, then converted to fraction per second. Bare soil is pft "0" and then there is a generic crop type that is not used (pft "16").  So, there are 17 pfts (0-16).
