Allowing short exposure time in the first three FPS iterations

That means our strategy is correct in first place.</li> <li>This evidence is also observed in longer exposure time convergence run.</li> <li>In another aspect, implementing the cobra-not-stop strategy will changed the strategy that has been working for many engineering runs.</li> <li>Therefore, implementing the cobra-not-stop at first three iteration strategy introduces another uncertainty and it should be another ticket.</li> </ul> <p>Giving that, let's make it simple. We solve this ticket first. Then creating another ticket to address Jeniffer's suggesting. </p> <p>This ticket is tested on the Unit Selector, close the ticket.</p> Development Rank 0|02qpjd:00r20060i200186403g
