Priorities are defined for the TSO WG:
1: Critical — will produce unusable/misleading 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.
Problems with current TSO3 step:

|Jump detection using TSO information|
Similar to the above, but do it at the group-level; detect jumps using TSO information. This is an idea proposed by Michael Regan. Pros: you don't rely on the reference files.

|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 (a) record trace movements (useful as external parameters to decorrelate lightcurves) and (b) extract the same portion of the spectrum at each time.|
