As for the Principal Investigator of the proposed project, the same information is required for each Co-Investigator, except for the user identification giving access to the proposals in the working memory. Use the commit button to commit the information to memory once the requested information has been completed.
At the bottom of each Co-I details page there are two buttons, ''Add Co-I'' and ''Delete Co-I Entry'' to add or remove a Co-I from the list of authors again.
Once done, and after committing all the information to memory, use the navigation tool to go back up by one level to the proposal level (§ 5.2). From there, either add more Co-Is if needed, or proceed to the first observation in the navigation tree and start entering observational details.
