ProMS（ Proposal Management System)

• A half of submission (including update and failure) was made in the last 2-3 hours.

How ProMS has been used

• An FAQ page• typical troubles in submitting proposals are listed

• Enlargement of the “magnitude” field in target list• more detailed description and automatic folding of a line

• TeX entry for backup targets• for efficient telescope operation

• PIs can register their CoI(s) to STARS via a Web page.

ProMS Improvements in 2010

• Web submission– PIs can fill in web forms and upload scientific justification and

finding chart in PDF files from a web page.

• Use of STARS ID to identify users.
