Repository Contents

eUCLID.txt

A text file containing a pandas DataFrame containing average time, longitude, latitude, tilt angle, velocity, ascpect ratio, half angle, and time at 21.5 solar radii for historical CMEs. These parameters can be used as inputs into CME propagation models for validation purposes.

croissant.py

A python module which contains all of the functions used in the repository. Import croissant as such for style consistency:

import croissant as cr

gcs_analysis.py

A python script which creates/updates eUCLID. In addition, gcs_analysis.py will calculate the spread in measurements of the same CME and saves these results as histograms and scatterplots in a path named "figdir" which must be defined on line 8 of gcs_analysis.py. This is useful in understanding the errors in the CME measurement process, and getting a sense of how accurate the measurements used are.

all_cmes.txt

A text file containing a list of dates and times of 2011 historic CMEs which are suitable for measurement and useable for eUCLID. The criteria for making this list was having a half width of over 30 degrees and a velocity of over 400 km/s.

carrots.txt

List of Carrington rotation start times, in seconds since the beginning of the unix epoch. Used for conversion from Carrington coordinates to Stonyhurst coordinates.

data

A series of folders containing GCS output files. gcs_analysis.py draws from these folders to create eUCLID.
