## Model Description

### Model Form

• This model produces a location within a quadrilateral area that is defined by three corner points.
• The fourth corner point will be automatically considered to produce a parallelogram.
• For further information on this model, refer to Rahimi and Mahsuli (2019) and Mahsuli et al. (2019).

• No

## Properties

### Object Name

• Name of the object in Rt
• Allowable characters are upper-case and lower-case letters, numbers, and underscore (“_”).
• The name is unique and case-sensitive.

### Display Output

• Determines whether the model is allowed to print messages to the Output Pane.

### Point 1 Location

• Location object for one corner of the area

### Point 2 Location

• Location object for another corner of the area

### Point 3 Location

• Location object for another corner of the area

### Theta 1

• $${\vartheta_1}$$ = Value between 0 and 1, typically a random variable uniformly distributed between 0 and 1.

### Theta 2

• $${\vartheta_2}$$ =Value between 0 and 1, typically a random variable uniformly distributed between 0 and 1.

### Depth

• Depth of the output location, in km

## Output

• Location object carried by a location response object
• The output is an automatically generated generic response object, which takes the object name of the model plus “Response”.
