Determine how long your observation as specified will take to execute by clicking on the "Observation Est... " button at the bottom of the AOR pop-up. If you are connected to our servers via the Internet, HSpot will return resource estimates in the a dialogue box. The most important number returned here is the AOR Duration. This is the wall-clock time that Herschel will require to execute the observation. You need to request this amount of time for the observation in your observing proposal.
On occasion the "Observation Est... " button may give a network error. This problem is usually transitory.
The information returned in the time estimate dialogue will depend on exactly which instrument/mode is being used but will include:
AOR Duration: This is the total wall-clock time required to execute the observation.
Estimator Version: This is the version of the software server that is calculating the resource estimates.
Integration Times: These are estimated on-source integration times in seconds for each array/module selected in the AOR.
