Description

Hello, if I want to use the following depreciation percentage (```0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1```) for ```depreciation``` and ```steam_power_depreciation``` when performing TEA, may I ask you which code should be used? It seems like I can only choose a few (such as ```MACRS7```) from the tutorials (https://biosteam.readthedocs.io/en/latest/API/TEA.html#:~:text=depreciation_schedules%3A%20dict,0.045%2C%200.045%2C%200.022%5D)%7D).

The TEA code is as follows.
```
tea = cls(
system=sys,
IRR=0.10,
duration=(2007, 2037),
depreciation='MACRS7',
income_tax=0.35,
operating_days=350.4,
lang_factor=None,
construction_schedule=(0.08, 0.60, 0.32),
startup_months=3,
startup_FOCfrac=1,
startup_salesfrac=0.5,
startup_VOCfrac=0.75,
WC_over_FCI=0.05,
finance_interest=0.08,
finance_years=10,
finance_fraction=0.4,
OSBL_units=OSBL_units,
warehouse=0.04,
site_development=0.09,
additional_piping=0.045,
proratable_costs=0.10,
field_expenses=0.10,
construction=0.20,
contingency=0.10,
other_indirect_costs=0.10,
labor_cost=2.5e6,
labor_burden=0.90,
property_insurance=0.007,
maintenance=0.03,
steam_power_depreciation='MACRS20',
boiler_turbogenerator=BT)
```
