Error about low-pressure steam

[zasddsgg]

a) Hello, in the cellulosic model, the temperature and pressure of low-pressure steam seems to be higher than the temperature and pressure of medium-pressure steam and high-pressure steam, and the heat transfer efficiency of low-pressure steam and medium-pressure steam is both 0.9. This does not seem right?

from biorefineries import cellulosic
import biosteam as bst
from biosteam import settings 
bst.nbtutorial()
cs = cellulosic.Biorefinery('corn stover ethanol')
lps = bst.settings.get_heating_agent('low_pressure_steam')
lps

mps = bst.settings.get_heating_agent('medium_pressure_steam')
mps

hps = bst.settings.get_heating_agent('high_pressure_steam')
hps

b) Could I consult you the source of data on the heat transfer efficiency of low pressure steam, medium pressure steam and high pressure steam in BioSTEAM (https://github.com/BioSTEAMDevelopmentGroup/biosteam/blob/master/biosteam/_heat_utility.py#L522-L536)?

Thanks for your help. Wish you a good day.
