... FEATURES OF OBTAINED IMAGES All images obtained by the TESIS have a number of artifacts, i.e., the dark current, flat field, blurring (related to the feature of input shutters and CCD matrices of the equipment), and frame damage caused by the entry of cosmic particles. In addition, poor accuracy of the spacecraft stabilization leads to the fact that separately taken images of the Sun have a ran dom displacement and rotation relative to the CCD matrix. ...
