The Proposal Submission Tool will allow you to submit all the necessary information to the HSC needed to process your science observing proposals. You do not need to be connected to the Internet to fill out the requested information. It can be entered, saved to local disk, and later modified if needed, as a "coversheet" (.cs) file. When you are ready to submit your proposal to the HSC you only need to ensure you are connected to the Internet, load a set of AORs into the AOR window, open the Proposal Submission Tool and open you coversheet file and click on Submit in the Proposal Submission Tool toolbar. Refer to the current Herschel Call for Proposals and website at http://herschel.esac.esa.int/ for more information about creating and submitting your Herschel observing proposal.
