• You will have access to all CfA proposals previously entered to this system.
• Changes may be made to any of your current proposals until the deadline. There is a "Submit" button now. Only submitted proposal will be taken into account.
• Information from a web form is immediately used to build a proposal cover page and errors are reported back to you so that they may be corrected before the proposal is finalized.
• You can view any of your proposals as Adobe Acrobat (PDF) files the way the TAC will see them.
• The TAC ranks submitted proposals 3-4 weeks after the proposal deadline.
• Telescope schedules should be available approximately one month before the beginning of each trimester (for Mt. Hopkins MMT and Ridge) or semester (for Magellan).
• If you are new to TDCApply, please read this help page.
• If the online help doesn't answer your questions, email them to the Telescope Data Center Staff.
