solarmach 0.2.3

Multi-spacecraft longitudinal configuration plotter

The Solar MAgnetic Connection Haus (Solar-MACH) tool is a multi-spacecraft longitudinal configuration plotter. This is the repository of the pip/conda package of Solar-MACH, called solarmach. For the corresponding streamlit repository, which is used for solar-mach.github.io, see github.com/jgieseler/Solar-MACH.

Installation

solarmach requires python >= 3.7.

It can be installed either from PyPI using:

pip install solarmach

or from conda using:

conda install -c conda-forge solarmach

Usage

from solarmach import SolarMACH, print_body_list

# optional: get list of available bodies/spacecraft
print(print_body_list().index)

# necessary options
body_list = ['STEREO-A', 'Earth', 'BepiColombo', 'PSP', 'Solar Orbiter', 'Mars']
vsw_list = [400, 400, 400, 400, 400, 400, 400]   # position-sensitive solar wind speed per body in body_list
date = '2021-10-28 15:15:00'

# optional parameters
coord_sys = 'Carrington'                         # 'Carrington' (default) or 'Stonyhurst'
reference_long = 273                             # longitude of reference (None to omit)
reference_lat = 0                                # latitude of reference (None to omit)
plot_spirals = True                              # plot Parker spirals for each body
plot_sun_body_line = True                        # plot straight line between Sun and body
long_offset = 270                                # longitudinal offset for polar plot; defines where Earth's longitude is (by default 270, i.e., at "6 o'clock")
reference_vsw = 400                              # define solar wind speed at reference
return_plot_object = False                        # figure and axis object of matplotib are returned, allowing further adjustments to the figure
transparent = False                              # make output figure background transparent
numbered_markers = True                          # plot each body with a numbered marker
filename = 'Solar-MACH_'+date.replace(' ', '_')  # define filename of output figure

# initialize
sm = SolarMACH(date, body_list, vsw_list, reference_long, reference_lat, coord_sys)

# make plot
sm.plot(
   plot_spirals=plot_spirals,
   plot_sun_body_line=plot_sun_body_line,
   reference_vsw=reference_vsw,
   transparent=transparent,
   numbered_markers=numbered_markers,
   long_offset=long_offset,
   return_plot_object=return_plot_object,
   outfile=filename+'.png'
)

# obtain data as Pandas DataFrame
display(sm.coord_table)
