We thank Rogalski1 for bringing to our attention the unexpectedly high detectivity (D*) value we reported2. As mentioned in the Matters Arising1, the D* value is higher than the value for a 2π field of view at 300 K background. On careful examination of the methodology and further recalculation, we realized that D* was overestimated, as suspected, as the consequence of one inaccurate assumption. Hence, we use this Reply to amend the values reported.
