# ASTR 410 Problem Set 04 Assessment Instructions

Inspect the student submission, this problem set, the solution key, the stated course policy, and any submitted code/data files.

## Standard
Award credit for dimensional consistency, correct Galactic interpretation, explicit assumptions, uncertainty or sensitivity analysis, and reproducible code. Record arithmetic slips separately from conceptual errors. Check that the student distinguishes level-2 literature values and level-3 instructor data from new measurements.

## Revision
Return actionable comments tied to a problem and rubric criterion. Students may revise and resubmit within one week with a change note; preserve the same high standards.
