The JWST (STScI) Pipeline, and in particular, the steps used by its TSO-mode are in constant development. In this page, we will keep track of the proposed enhancements to the pipeline by the TSO WG. Status of each of the proposed enhancements can be:

Priorities are defined for the TSO WG:
1: Critical — will produce unusable results for TSOs.
2: High — will produce sub-optimal results for TSOs.
3: Low — will produce slightly offset results for TSOS.

| TSO3 Outlier Detection | Currently, the JWST pipeline does not properly use TSO information to reject outliers (e.g., jump step or current tso3 outlier rejection — see Jira tickets). Proposed to implement HST/STIS algorithm developed by Nikolay Nikolov on JWST TSO pipeline. |

| Correct jitter spectral movement prior to photom step | If jitter is an issue during JWST observations, then the photom step will incorrectly apply photometric flux standarization to the wrong wavelengths, introducing time-dependant systematics. TSO WG reps think turning off the photom step would be ideal, but not generic solution. Correcting those jitters prior to the photom step would be a solution. |

| Spectral tracing | Pipeline needs to perform spectral tracing of TSOs in order to record and properly extract the same portion of the spectrum at each time. |
