Some keywords:

magmaptype

• CRMAP input magnetogram is a synoptic one (WSO)
• SMAP input magnetogram is a synchronic one (NSO and ADAPT)

magmapcarr

Carrington rotation of the magnetogram. Only used for CRMAP value of magmaptype

magmapdate

Date of the magnetogram. Only used for SMAP value of magmaptype.
Date format is YYYYMMDDHHMMSS.

magmappath

Path of magnetogram where corfield is launched.
For instance: 'dir.input/wso2164.txt'.

magmapsrc

Magnetogram source. 'WSO' or 'NSO' or 'ADAPT'.

magmapext

Magnetogram extension.

• 'TXT' for WSO
• 'FITS' for NSO or ADAPT

write3d

• T will write datacube ascii file
• F will not

writelines

• T will write fieldlines ascii file, one file per fieldline
• F will not

writelines1file

• T will write fieldlines in a single ascii file
• will not

out_frame

• 'NAT' Take the magnetogram as it comes.
• 'CAR' Center the magnetogram so that 0 Carrington longitude is at the center.

seed_pos

Define where fieldline integration starts.

• 'top' Integration starts from source surface to solar surface.
• 'bot' Integration starts from solar surface to source surface.

seed_type

• 'GRID' Seed points for fieldlines are automatically placed on a regular grid corresponding to magnetogram resolution.
• 'LIST' Seed points for fieldlines are defined by user (see seed_phi and seed_the keywords).

seed_n

Only for LIST value of seed_type. Number of seed points.

seed_phi

Only for LIST value of seed_type. List of longitude of seed points.
Example: seed_phi = 90., 180.

seed_the

Only for LIST value of seed_type. List of latitude of seed points.
Example: seed_the = -10., 10.
