• Looked at the mode mismatch using cavity_mismatch_table().
• Compared these finesse_ligo factory model mismatch values with those of the aLIGO katscript model.
• The latter does not have the cavity_mismatch_table(), looked at both models' mismatch values using cavity_mismatch().
• Ascertained that there is less mode mismatch in the katscript model (~10^-2) as compared to the factory model (~10^-6).
• Mismatch values are starkly different, not just for (PRC, XARM) but also for others like (OMC, XARM).

• Analysed the locking process for factory model and katscript model to find minor differences in the order.
• Tried applying the katscript locking function to the factory model and still seem to get the same results. (to recheck)
