These catalogs list some parameters of the YOGIS coronal green-line data calculated from the APRIL method. The descriptions for each column are as follows:

OBS-TIME:        Observation time of the coronal data in UT.
Image Size:      Pixel size of the coronal image.
DX:              Horizontal translation of the coronal image in the accurate registration step. (Unit: Pixel)
DY:              Vertical translation of the coronal image in the accurate registration step. (Unit: Pixel)
K:               Scaling factor of the coronal image in the accurate registration step.
Theta:           Rotation angle of the coronal image in the accurate registartion step. (Unit: Rad)
R_SUN:           Solar radius. (Unit: Pixel)
X_SUN:           Solar center coordinate in the horizontal direction. (Unit: Pixel)
Y_SUN:           Solar center coordinate in the vertical direction. (Unit: Pixel)
R_Occullter:     Occulter's radius. (Unit: Pixel)
X_Occulter:      Occulter's center coordinate in the horizontal direction. (Unit: Pixel)
Y_Occulter:      Occulter's center coordinate in the vertical direction. (Unit: Pixel)
