We have just updated our On-the-fly time calculator to v10.0, fixing a mistake in the time estimation that we had introduced in the previous version. As a consequence, now time estimates can be considerably longer, especially for deep integrations where many coverages of the scanning area are needed.
The on-off integration time calculator remains unchanged (currently in its V7.3) and was not affected by this issue.
We apologize for the inconvenience that this might have caused to users proposing to APEX in the last period. We want to thank L. Pagani and A. Belloche for pointing out this error in our code.
