ANG_ROT |
Array of three rotation angles (in degrees) used to improve the generation of the
torque-variation pole confidence contours, since these can be inaccurate when the
bulk of the torque-variation ensemble is close to any of the polar regions. The
angles instruct MYRIAM to perform the three elemental rotations that seek to center
and horizontally flatten the torque-variation ensemble on 0°N--0°E, where the
contouring is more accurate.
|
CTR_PATH |
String path to a plain-text file containing the plate contour coordinates as two
columns: [1] longitude and [2] latitude values, both expressed in degrees.
|
DEF_DISTANCE_km |
Value used to set a deformation buffer width (in kilometers) across the plate
boundary. The boundary region has a linearly-decreased Euler vector magnitude,
acting as a damped rigidity, as yielding an overall smaller torque-variation
estimate.
|
DIR_dM_PPD | |
DIR_MTX_w2M | |
DIR_OUTPUTS |
Path to an existing directory in which all the output folders and files are stored.
|
DIR_TMP | |
DM_CNTR_BINS |
Array of values used to constrain the spatial statistical distribution of the
torque-variation poles, and thus modify the resolution of the output pole
confidence-contours: [1] resolution of the 2-D histogram grid in degrees,
[2-3] minimum and maximum longitude of the grid, and [4-5] minimum and maximum
latitude of the grid.
|
DM_CNTR_PERCENT |
Array of confidence levels (expressed as percentages) used by MYRIAM to calculate
confidence contours of the torque-variation pole.
|
DM_MAGHIST_BINS |
Number of bins used to obtain the histogram showing the distribution of the
torque-variation magnitude.
|
EVo_PATH |
Same as EVy_PATH, but for the older Euler vector. This input is
optional, i.e., if omitted MYRIAM will assume that EVy_PATH
already contains the difference between two Euler vectors at two particular stages.
|
EVy_PATH |
String path to a 3-column plain-text file containing an ensemble of sampled
Cartesian values of the younger Euler vector, expressed in deg/Myr (degrees
per million year). Alternatively, MYRIAM can sample its own ensemble from a
singular Euler vector stage, by supplying a 10-column single line containing:
[1-2] Euler pole longitude and latitude in degrees, [3] angular velocity
magnitude in deg/Myr, [4-9] elements of the covariance matrix associated
with the Euler vector ensemble, in rad²/Myr², and [10] size of the ensemble.
|
FRACTION_HA |
Value between 0 and 1 that sets the vertical fraction of the region utilized
to define the depth-average viscosity of the asthenosphere using the model
PM_v2_2012 by Priestley and McKenzie, 2013.
|
GRID_RES |
Value for the grid resolution of the plate's base, expressed in degrees. That is,
the longitudinal/latitudinal spacing of the grid.
|
HL_km |
Value of the lithosphere thickness (i.e., depth of the lithosphere-asthenosphere
boundary), expressed in kilometers.
|
MATRIX_PATH | |
MODEL_LABEL | |
muA |
Average value of the asthenosphere viscosity, expressed in Pa · s.
|
muM |
Average viscosity value of the lower part of the upper mantle,
expressed in Pa · s.
|
OUTPUT_LABEL |
String that is added to all output directories and input report file to help the
user setting apart iterations of the software without risking overwrite.
|
OVERWRT_OUTPUT |
Boolean that instructs MYRIAM whether to overwrite files. If false, MYRIAM will ask
whether overwriting is desired, when encountering folders with the same name as the
current intended output.
|
PLT_LABEL |
String that serves as plate label, and is added to all output directories and
file names. It may also serve as plate identifier, which allow MYRIAM to use
build--in plate contours from Matthews et al., 2016.
|
PYTHON_PATH |
String path to a Python3 executable in the running machine, used by MYRIAM to generate
PNG figures.
|
REGION_muA_LV |
Rectangular geographic region for calculating lateral variations of the
asthenosphere. If omitted, MYRIAM used the whole globe as region. If empty,
a uniform asthenosphere viscosity is used as opposed to a laterally-varying one.
|
RUN_LABEL | |
SAVE_ENS |
Boolean that instructs MYRIAM whether to save or not the output torque-variation
ensemble in a plain-text file.
|
STG_IDX_1 |
First integer element of STG_IDXs.
|
STG_IDX_2 |
Second integer element of STG_IDXs.
|
STG_IDXs |
Array of two integers, which serve as indexes to identify the two particular
Euler-vector stages used. File labeling prevents overwriting, e.g., when
using the same plate but different Euler vectors.
