    10 - This calibration is performed to calibrate the center of the target star (hidden by the coronagraph) in order to provide a reference input for frame derotation to be performed in post-processing.

    16 - TBW+TBC
    1716- Offset of the ASM generating multiple satellite spots in the focal plane + AO closed-loop + coronagraph
    18 - The required specifications of the corresponding image are the presence of at least 4 satellite spots placed symmetrically with respect to the star, at separation within 5 and 15 lambda/D, with FWHM < 45 mas and separation precision < 6 mas.
    19 - Either KL#62 or KL#119 is applied to the ASM on target acquisition to generate the satellite spots. Find the centroids of the spots and fit a circle to them. The center of the circle is the extrapolated star position behind the coronagraph.
     17- The required specifications of the corresponding image are the presence of at least four satellite spots placed symmetrically with respect to the star, at separation within 5 and 15 lambda/D, with FWHM < 45 mas and separation precision < 6 mas.
     18- Either KL-62 or KL-119 is applied to the ASM on target acquisition to generate the satellite spots. Find the centroids of the spots and fit a circle to them. The center of the circle is the extrapolated star position behind the coronagraph.
