Instructions for Submitting Keck Proposals

Dear UC Keck Observers,

1. Proceed to the Keck Observer Login Page. Login using an existing Keck observer account (or, if necessary, create a new account and login). Find the Cover Sheets section and submit a new Cover Sheet, or select an existing Keck Cover Sheet to be updated and re-used. Follow the instructions to prepare and submit the Keck Proposal Cover Sheet.

The "Allocating Institution" should be one of the UC options (in order to send the Cover Sheet to the UCO web server). Please ensure that the e-mail addresses of the PI and all Co-Is are valid; this is important for subsequent processing of the proposal by the UCO web server.

Take note of the Keck Cover Sheet Id that is assigned for the proposal.

After submission at Keck there is a delay, typically of some minutes, while the Cover Sheet is transferred from the Keck web server to the UCO web server for the next steps. The UCO web server can only accept proposals after it receives the Cover Sheet from Keck, so be sure to do this step before the deadline.

2. Prepare the body of the proposal containing the Scientific Justification, figures, Technical Comments, Results from Previous Keck Runs.

The top line of the proposal must contain the PI name, the assigned Keck Cover Sheet Id, and proposal title.

This proposal must be a PDF file.

3. Go to the UC Keck Proposal web page.

Enter the e-mail address of the PI (or a Co-I) as listed on the Keck Cover Sheet, the Keck Cover Sheet Id, and click the "Proposer Login" button.

Click the "Submit (or resubmit) a TAC Proposal File" button. Use the web browser file chooser to select the PDF file with the proposal that is on the local machine running the browser. The submission web page will give an opportunity to review the PDF file that has just been uploaded.

Note: The UCO web server will accept multiple revisions of the proposal PDF file until the deadline; simply return to the web page and submit the new version. The Keck web server will accept edits to modify an existing Cover Sheet; that will preserve the Cover Sheet Id and the connection with the proposal submitted to the UCO web server. The instructions for this are found at the Keck Observer Account web pages. (If a new Cover Sheet Id is created at Keck then the UC web server must receive a proposal for that new Cover Sheet Id.)

4. After the proposal has been uploaded to the UCO web server it will send e-mail confirmation to the PI and all Co-Is listed on the Keck Cover Sheet. Please watch for this confirmation.

If there are any problems, or suggestions for improving the proposal system, please contact

Director of UC Observatories
