ACS Data Analysis

The ACS Cycle 18 Instrument Handbook contains the primary guide to ACS data characteristics and analysis. However, if you are just beginning, the best place to start is with the GO-HST Primer for Cycle 18.

The Calacs Data Handbook chapter provides instructions on how to run the acs calibration software.

The ACS Data Handbook is the primary reference for data format and analysis information. Versions with all chapters and ACS chapters are also available in PDF format.
