4.2.12. Data Book Definitions

The section in pyCart.json labeled “DataBook” is an optional section used to allow pyCart to create a data book of relevant coefficients and statistics. It enables collecting key results and statistics for entire run matrices into a small number of files.

"DataBook": {
    // List of components or data book items
    "Components": ["fuselage", "wing", "tail", "engines", "P1"],
    // Number of iterations to use for statistics
    "nStats": 50,
    "nMin": 200,
    // Place to put the data book
    "Folder": "data"
    // Sorting order
    "Sort": ["mach", "alpha", "beta"],
    // Information for each component
    "fuselage": {
        "Type": "FM",
        "Targets": {"CA": "WT/CAFC", "CY": "WT/CY", "CN": "WT/CN"}
    },
    "wing":     {"Type": "FM"},
    "tail":     {"Type": "FM"},
    "engines":  {"Type": "Force"},
    // Information for a point sensor
    "P1": {
        "Type": "PointSensor",
        "Points": ["P101", "P102"],
        "nStats": 20
    },
    // Target data from a wind tunnel
    "Targets": {
        "WT": {
            "File": "data/wt.csv",
            "RunMatrix": {"mach": "Mach"},
            "Tolerances": {
                "mach": 0.02, "alpha": 0.25, "beta": 0.1
            }
        }
    }
}

All settings, their meanings, and their possible values are described the corresponding Cape DataBook section.
