 deg -9.78000000000000000
ar0.min_ds

ar0.max_npts 
Maximum points of the mesh resolution.
 Set this value to change the maximum number of points used to resolve the smaller side of the selected region. This ensures that for every size of the box you draw, it will be resolved appropriately. Changing this value affects the number of points required to resolve the region as well as the smoothness of the magnetic field. 70
ar0.ds

2.3 RBSL Flux Rope Designer 
A set of parameters for the flux rope selection in the RBSL Flux Rope Designer.
Name Description Caveats Units Default Value or Actual Value Valid Min Valid Max
fr0.fp_pos_lon 
Positive longitude of the foot point of the flux rope.
 deg 277.33
fr0.fp_pos_lat 
Positive latitude of the foot point of the flux rope.
 deg -3.99
fr0.fp_neg_lon 
Negative longitude of the foot point of the flux rope.
 deg 274.79
fr0.fp_neg_lat 
Negative latitude of the foot point of the flux rope.
 deg -6.11
fr0.apex_height 
Apex height of the flux rope.
 Height of the default axis peak above the photosphere. The default axis peak is located at the flux-rope center. Rs 0.0250
fr0.fract_width 
Fractional width of the flux rope.
 Ratio of the flux rope minor radius (thickness) to the apex height. Thin flux ropes are likely to become kink-unstable. To suppress the instability, a value of 0.7 or larger should be chosen. Rs 0.7000
fr0.rbsl_frac_curr 
Fraction of the flux-rope current with respect to the 'optimized' current.
 A factor of 1 would minimize the total Lorentz forces along the body of the initial flux-rope geometry. In practice, the exact threshold for eruption depends on the details of the configuration and needs to be established through experimentation. Typically, numbers lower than the range 1.2 to 1.5 yield a stable configuration, while numbers above that lead to an eruption. The default value (1.5) should produce an eruption in most cases. 1.500
fr0.axial_current 
Axial current of the flux rope converted to code units.
 Because of how we choose to define the RBSL path, the sign signifies whether the current flows from the negative footpoint to the positive footpoint (+) or the positive footpoint to the negative footpoint (-). This will match what is in the MAS input file. 2.768552
fr0.insertion_delay_mins 
Insertion delay time of the flux rope in the final CME simulation.
 Use this only if multiple CMEs are modeled. The maximum delay time is 240 minutes. Note: This only applies to the CME simulation in Step 4, not to the zero-beta runs in Step 1. min 0.00
fr0.rbsl_minor_r 
Minor radius (half diameter) of the flux rope.
 Rs 0.0175
fr0.rbsl_hmod_pos 
The position of the peak of the flux-rope axis. 0 is the left-most point and 1 is the right-most point along the axis.
 0.50
fr0.rbsl_hmod_width 
The width of the axis peak.
 0.50
fr0.rbsl_hmod_amp 
The amplitude of the axis peak.

Maximum points of the mesh resolution.
 Set this value to change the maximum number of points used to resolve the smaller side of the selected region. This ensures that for every size of the box you draw, it will be resolved appropriately. Changing this value affects the number of points required to resolve the region as well as the smoothness of the magnetic field.
ar1.ds 
Mesh resolution delta.
 This is the mesh resolution (in radians) that is used to resolve the selected region. It is determined by the size of the selected region and the two mesh parameters (minimum delta and maxim number of points). radians
ar1.cpal 
 	

Color map of the Active region plot.
 blue_red
ar1.cmin 
Minimum scaling of the Active region map plot.
Gauss
ar1.cmax 
Maximum scaling of the Active region map image.
 Gauss
ar1.br_r_scale 
PIL Radial Height.
 Radial height at which the PIL is computed. Greater radial height value gives simpler PILs. A typical choice ranges from 1.00 to 1.02 Rs.
ar1.name 
 	

User-specified name of the second active region.
2.2 Polarity Inversion Line (PIL#2) 
A set of parameters for an additional PIL in the RBSL Flux Rope Designer. The CORHEL-CME code allows modeling of up to two events concurrently, with the second one being optional.
Name Description Caveats Units Default Value or Actual Value Valid Min Valid Max
nl1.lon0 
Starting longitude of the second Polarity Inversion Line.
 deg
nl1.lat0 
 	

Starting latitude of the second Polarity Inversion Line.
 deg
nl1.lon1 
Ending longitude of the second Polarity Inversion Line.
 deg
nl1.lat1 
 	

Ending latitude of the second Polarity Inversion Line.

nl1.bp_cmin 
Minimum scaling of the External Field (Bp) plot.
 Gauss
nl1.bp_cmax 
Maximum scaling of the External Field (Bp) plot.

2.3 RBSL Flux Rope Designer (#2) 
A set of parameters for an additional flux rope in the RBSL Flux Rope Designer. The CORHEL-CME code allows modeling of up to two events concurrently, with the second one being optional.
Name Description Caveats Units Default Value or Actual Value Valid Min Valid Max
fr1.fp_pos_lon 
Positive longitude of the foot point of the second flux rope.
deg
fr1.fp_pos_lat 
Positive latitude of the foot point of the second flux rope.
deg
fr1.fp_neg_lon 
Negative longitude of the foot point of the second flux rope.
 deg
fr1.fp_neg_lat 
 	

Negative latitude of the foot point of the second flux rope.
 deg
fr1.apex_height 
 	

Apex height of the second flux rope.
 Height of the default axis peak above the photosphere. The default axis peak is located at the flux-rope center. Rs
fr1.fract_width 
 	

Fractional width of the second flux rope.
 Ratio of the flux rope minor radius (thickness) to the apex height. Thin flux ropes are likely to become kink-unstable. To suppress the instability, a value of 0.7 or larger should be chosen. Rs
fr1.rbsl_frac_curr 
Fraction of the flux-rope current with respect to the 'optimized' current.
 A factor of 1 would minimize the total Lorentz forces along the body of the initial flux-rope geometry. In practice, the exact threshold for eruption depends on the details of the configuration and needs to be established through experimentation. Typically, numbers lower than the range 1.2 to 1.5 yield a stable configuration, while numbers above that lead to an eruption. The default value (1.5) should produce an eruption in most cases. 1.5
fr1.axial_current 
Axial current of the flux rope converted to code units.
 Because of how we choose to define the RBSL path, the sign signifies whether the current flows from the negative footpoint to the positive footpoint (+) or the positive footpoint to the negative footpoint (-). This will match what is in the MAS input file.
fr1.insertion_delay_mins 
Insertion delay time of the second flux rope in the final CME simulation.
 Use this only if multiple CMEs are modeled. The maximum delay time is 240 minutes. Note: This only applies to the CME simulation in Step 4, not to the zero-beta runs in Step 1. min 0
fr1.rbsl_minor_r 
Minor radius (half diameter) of the second flux rope.
 Rs
fr1.rbsl_hmod_pos 
The position of the peak of the flux-rope axis. 0 is the left-most point and 1 is the right-most point along the axis.
fr1.rbsl_hmod_width 
The width of the axis peak.
fr1.rbsl_hmod_amp 
The amplitude of the axis peak.
