COS GTO and WFC3 ERS Duplication Checking

The COS GTO and WFC3 ERS programs were inadvertently not included in the duplication checking web page and the Planned and Archived Exposure Catalog. An Exposure Catalog for the GTO and ERS programs is linked as an excel spreadsheet from both the COS GTO, and WFC3 ERS webpages. Proposers of COS or WFC3 programs should use this Catalog for additional duplication checks.

We would also like to bring to your attention several other items on the Late Breaking News Section, which can be found on the Cycle 17 Announcement page.
