Let me teach you ;)

      *  @param symbol The asset symbol of the created token
      *  @param schedule_time The time the token is applicable
      *  @param json_emission_unit A JSON representation of an emission unit
      *  @param interval_seconds The seconds between intervals
      *  @param interval_count The number of intervals
      *  @param lep_time The time of the left endpoint
      *  @param rep_time The time of the right endpoint
      *  @param lep_abs_amount The absolute emission amount of the left endpoint
      *  @param rep_abs_amount The absolute emission amount of the right endpoint
      *  @param lep_rel_amount_numerator The relative emission numerator of the left endpoint
      *  @param rep_rel_amount_numerator The relative emission numerator of the right endpoint
      *  @param rel_amount_denom_bits The about of bits to shift for the relative denominator
      *  @param remove Indicates whether an emission should be added or removed
      *  @param floor_emissions Indicates whether we should consider the lowest or highest value with regards to relative and absolute emissions
      *  @param broadcast To broadcast this transaction or not

These are the parameters you can set for an smt.
