(color online) Optimization of sensitivity function g(t) for interleaved Ramsey-CPT clock. Panels (a) and (c) respectively show sensitivity function g(t) for vapor cell 1 and cell 2 before optimization. Panel (e) is the numerical sum of panels (a) and (c) for the unoptimized double cell. Panels (b) and (d) respectively show sensitivity function g(t) for vapor cell 1 and cell 2 after optimization. Panel (f) is the numerical sum of the two sensitivity functions for the optimized double cell.
