Hi, I'm having a problem with the Python version of Orekit. I used the Python version of Orekit's MP model for atmospheric refraction correction. However, the software prompts me that 'MendesPavlisModel' object has no attribute 'getParameters'. Can you help me? Here is my code.

• import orekit
• vm = orekit.initVM()
• from org.orekit.models.earth.troposphere import MendesPavlisModel
• latitude=FastMath.toRadians(30.67166667)
• longitude=FastMath.toRadians(-104.0250)
• height=2010.344
• pressure=798.4188
• temperature=300.15
• humidity=0.4
• lambdad=0.532
• point=GeodeticPoint(latitude, longitude, height)
• date=AbsoluteDate(2009,8,12, TimeScalesFactory.getUTC())
• elevation=15.0
• MP_Model=MendesPavlisModel(temperature, pressure,humidity, lambda)
• computedDelay = model.computeZenithDelay(point, model.getParameters(), date)
