Small Defects

• Focus Profile 3 should have had a determinable best focus position but was rejected during QC checks  (22:18).  Focus Profile 3 (C/2020 R7 (ATLASS) ) was completed using 14 points. Best focus was initially taken as 2756 based on Modified Best Focus.  (vs FP (Curve Fit) of 2628 ), however the best focus position was then rejected during final Profile review due to "Ambiguous result".  Problem seems to have arisen because of the effects of a single rogue point (Point 1/14 at 3658,  FWHM 6.33,  Max 413), see Fig 1.  Fixed in AstroMain 3.66.6, points are invalidated when doing Narrow Search and MaxPixel(J) < PeakMaxPixel / 2 And YHFD(J) - YFWHM(J) > 5.   The profile was replayed and it was confirmed  that point 1/14 is recognised as being rogue and is excluded from the best curve fit.and that the profile passes all QC checks including the latest one (RmsE (0.53)  < 1.25) see Fig 2.
  Closed 2024-03-20 (AstroMain 3.66.6).
