**Comments:**
- High mass signals: The Ks posterior (with symmetric Ks prior) peaks around zero in f_imr runs while they are mostly biased towards negative Ks in f_isco runs. This can attributed to the fact that for high mass signals the additional SNR coming from MR part helps breaking the degeneracies between parameters and results in more symmetric Ks posteriors.
- Low mass signals: The effect of f_imr vs f_isco is minor in low mass signals like GW151226 because the contribution from MR part is minor.

## Effect of cutoff frequency
We perform an injection study to see the effect of the upper cut-off frequency of the analysis. Fixed M=15Msun with q=2 and fixed spins of (0.6, 0.3). Considered spin-dependent upper cut-off, inspiral only cut-off of the IMRPhenom waveforms and the full IMR cut-off frequency.

**Comments:**
* Increasing cutoff increases the matched-filter SNR of the recovered signal [(SNR comparison)](https://ldas-jobs.ligo-la.caltech.edu/~abhirup.ghosh/kappa_review/snr_cutoff/combinedsummarypages/html/Comparison_matched_filter_snr.html). Appropriately, [posteriors on dquadmons](https://ldas-jobs.ligo-la.caltech.edu/~abhirup.ghosh/kappa_review/snr_cutoff/combinedsummarypages/html/Comparison_dquadmons.html) get more constrained as one would intuitively expect.
* What are the possible systematic biases you might get from not extending the parameterization to the merger-ringdown region?
**Comments (Krishnendu):**
* Yes, we agree and is consistent with what we also find.
* In order to understand the systematic biases arise due to the truncation we have not performed any particular test. In other words, the only effect we focussed is also the SNR effect.
## Effect of spin magnitude
We perform an injection study to see the effect of the upper cut-off frequency of the analysis. Fixed M=15Msun with q=2 and fixed spins of (0.9, 0.8), (0.6, 0.3), (0.4, 0.3) and (0.2, 0.1). Truncated the analysis at the inspiral transition frequency and the value is 244Hz

**Comments:**
* In all four cases, spins are aligned with the orbital angular momentum. So, contribution to the spin-induced quadrupole moment scalar should increase with chi_eff. Looking at the plots for chi_eff and dquadmons, we indeed see that as chi_eff increases, constraints on dquadmons become tighter.
## Effect of spin orientations
We perform an injection study to see the effect of the upper cut-off frequency of the analysis. Fixed M=15Msun with q=2 and fixed spins of (0.6, 0.3), (0.6, -0.3), (-0.6, 0.3) and (-0.6, -0.3). Truncated the analysis at the inspiral transition frequency and the value is 244Hz

**Comments:**: There is a detailed discussion on the effect of spin-directions in Sec. III B.1 of Krishnendu et al PHYS. REV. D 100, 104019 (2019), using an additional match/fitting factor investigation.
## Effect of mass ratio
The analysis is performed for systems with a fixed spin magnitude of (0.4, 0.3). We choose systems with an inspiral only signal to noise ratio of ~12.

**Comments**: For equal mass binaries, systems with both spins anti-aligned wrt the orbital angular momentum, are better for constraining the parameter space of \delta\kappa_s < 0, while systems with both spins aligned with the orbital angular moment are better for constraining the parameter space for \delta\kappa_s > 0. For highly unequal mass binaries, the spin on the primary compact becomes significant in determining chi_eff, and depending on its orientation wrt \vec{L} determines the constraints on the parameter space.

**Comments (Krishnendu):**
* We notice that the recovered matched-filter SNR in each case is different for systems even though the injections assume a fixed SNR injection of 43. This offset is primarily due to the fact that the injections are made using full IMR frequencies and recovery is truncated at a frequency which is a function of the total mass of the system. For low mass systems, we expect this offset to be less. A figure is made to support this argument [SNR_diff_freq_diff_M.pdf](uploads/bc87af98a6b2474e342f3f5b97ff1781/SNR_diff_freq_diff_M.pdf).
**Comments:**
**Notice that for the runs done with a different version of the code the results are unaffected**
