Depth of Martian Magnetization From Localized Power Spectrum Analysis

Supplementary data to the article

    Gong, S. and Wieczorek, M. (2021) Depth of Martian Magnetization From
      Localized Power Spectrum Analysis, J. Geophys. Res. Planets

This archive contains the final inversion results for the employed magnetized
caps model using a magnetic field that expanded to degree and order 134. For
each localized analysis, the bandwidth and angular radius of the window were
17 and 20 degrees, respectively, which yields 8 localization windows that
concentrated more than 70% of the power with the region of interest. The
analyses were performed at 150 km altitude and on an equally spaced grid with a
spacing corresponding to 10 degrees of latitude.

FILE DESCRIPTIONS

20_17_8_134_150.dat

    This file contains the best fitting values and the corresponding reduced
    chi^2 value of the inversion. The first two columns correspond to the
    latitude and longitude, and the third to sixth columns correspond to the
    best fitting values of the angular radii (in km) of the magnetized caps,
    the magnetization depth (in km), the square root of the metric NV^2
    (in A m^2), and the reduced chi^2 value of the best fitting model at each
    location, respectively.

20_17_8_134_150_lower.dat
20_17_8_134_150_upper.dat

    These two files contain the 1-sigma lower and upper limits of the
    parameters. For each file, the first two columns correspond to the latitude
    and longitude, and the third to fifth columns correspond to the 1-sigma
    lower or upper limits of the angular radii (in km) of the magnetized caps,
    the magnetization depth (in km), the square root of the metric NV^2
    (in A m^2), respectively. The last column corresponds to the 1-sigma
    confidence level of the reduced chi^2 that were obtained from Monte Carlo
    simulations. The 1-sigma lower and upper limits were set to -1e+100 when the
    minimum reduced chi^2 value of the best fitting model was above this 1-sigma
    confidence level.
