Full-disk H-alpha image without limb darkening: We have applied the same techniques as for our Ca K-line images to produce this residual image in H-alpha. It shows the residual structure of the disk after subtraction of an empirical `limb darkening' function. The contrast is enhanced to show the details better.
Full-disk K-line image without limb darkening: We have applied the same techniques as for our other images to produce this residual image in K-line. It shows the residual structure of the disk after subtraction of an empirical `limb darkening' function. The contrast is enhanced to show the details better.
Full-disk white light image without limb darkening: We have applied the same techniques as for our Ca K-line images to produce this residual image in white light. It shows the residual structure of the disk after subtraction of an empirical `limb darkening' function. The contrast is enhanced to show the details better.
Full-disk white light image with limb darkening: We have not applied the same techniques as for our Ca K-line images to produce this image in white light. It shows the structure of the disk without subtraction of an empirical `limb darkening' function. The contrast is normal to show the details normally.
