SoftwarePhaseCorr 3.0, JPEG Composer 1.0, Corona 3.0, Sofo ACC 6.0
NoteSOHO LASCO C2 image file name: 22160103.fts
Calibration file for C2 vignetting correction: c2_or_vig_960611_v01.fts
OrientationThe image is presented in the orientation as it was visible from the aircraft. The image must be rotated 174.5° anticlockwise to achieve the standard orientation i.e. North top, East left
