There are three places we use nMatchMin in the McsCmd.py. When fitting outer ring, we use 10% as well as the all fiducial fibers. However, in Eng-20 we found the convergence of cobra gets bad because of bad FF matching. There is discussion on making nMatchMin value higher. The code is attached.
ffid, dist = pfiTransform.updateTransform(mcsData, self.fidsOuterRing, matchRadius=8.0, nMatchMin=0.1)
nMatch = len(np.where(ffid > 0)[0])
self.logger.info(f'Matched {nMatch} of {nFidsOuterGood} outer ring fiducial fibres')
nsigma = 0
pfiTransform.nsigma = nsigma
pfiTransform.alphaRot = 0
self.logger.info(f'Re-calcuating transformation using ALL FFs.')
for i in range(2):
ffid, dist = pfiTransform.updateTransform(mcsData, self.fidsGood, matchRadius=4.2,nMatchMin=0.1)
