Welcome

The PFS Target Uploader is a web app to validate and submit the target list supplied by users with an observing time estimate by a pointing simulation.

Info

January 26, 2026 (HST)

Updates for S26B Call for Proposals include the following changes:

  • The last 7 characters of the Upload ID are appended to ob_code automatically when the target list is loaded.
  • Flux values are checked against the bright magnitude limits.
  • Flux values are checked to detect potential unit mismatches.
  • Target duplication checking within the target list has been added to remind users to verify their target list.
  • Pointing simulations are updated to use a realistic focal plane configuration.

Table of Contents

  • Prepare Your Target List

    Understand the file format and contents of your input target list required for PFS observation.

  • Validate Your Target List

    Check if your input target list meets the requirements and understand errors and warnings.

  • Simulate PFS Pointings

    Estimate required observing time to complete your targets by using the PFS pointing planner.

  • Submit Your Targets

    Submit the target list and receive a Upload ID.

  • FAQ & Known Issues

    Check frequently asked questions and known issues first when you have any troubles with the app.
