ICON: [[File:huyg_src_icon.png]]
MODULE: [[EM.Tempo]], [[EM.Terrano]], [[EM.Illumina]], [[EM.Picasso]], [[EM.Libera]]
FUNCTION: Defines an equivalent Huygens source based on a specified Huygens surface data file
TO DEFINE A HUYGENS SOURCE:
# Right-click on the '''Huygens Sources''' item in the navigation tree.
# Select '''Import New Source...''' to open up Window's Open Dialog. The file extension is automatically set to ".HUY".
# Browse your folders to find the desired Huygens surface data file. Select it and click the '''Open''' button of the dialog.
# A Huygens source box appears in the project workspace. You can open the property dialog of the Huygens source and change its location and orientation.
PYTHON COMMAND: huygens_src(label,filename,[set_lcs,x0,y0,z0,x_rot,y_rot,z_rot])
