JWST commissioning has provided many datasets that astronomers may find useful. Datasets collected during the six month commissioning process provide examples of observation modes to help astronomers become familiar with data formats, the pipeline, and known artifacts, as well as to test their analysis methods. Some commissioning data may also provide serendipitous scientific value. Here we highlight some of the datasets that have been identified by the mission team as potentially useful to astronomers.

Caveats
- These commissioning datasets were not originally intended for detailed scientific analysis, and may have artifacts, non-optimized instrument configurations, and other issues that were addressed during commissioning.
- Datasets obtained prior to the completion of OTE mirror alignment are particularly susceptible to significant variable wavefront error. Fine phasing of the telescope occurred on 11 March 2022. The wavefront stabilized after MIRI achieved operating temperature on 07 April 2022.
- Help for understanding the science content of these programs should be directed to https://stsci.service-now.com/jwst. The JWST Help Desk has very limited resources to investigate issues specific to the content of the data obtained during commissioning and will be prioritizing Cycle 1 support.
| Tip | ||
|---|---|---|

All MIRI commissioning data taken after a detector health and functionality checkout on DOY 101 (11 April 2022) may be of value to the scientific community; references are provided here to several example programs. |
| Note |
|---|
The total volume of commissioning data exceeds 46 TB. Data from even a single program may take a long time to download, and will consume considerable space on local storage. We strongly recommend exploring the subset of programs and observations identified here in the Highlighted Data section, and restricting your search and download to only the observations denoted in the table. Observation numbers are denoted with a "-o###" in observation IDs or file names for supported products. |
Highlighted Data
| Note |
|---|
The retrieval scripts have been removed from AWS, since data are reprocessed over time with updated calibrations and pipeline versions. |
This table still serves as a useful reference for commissioning observations that the mission and instrument teams have identified of being the most useful. We recommend you use the astroquery.mast Python library to search for and download the data products associated with these observations.
