Stage 1: Detector Processing TSO testing
| Pipeline step | NIRISS status | NIRISS comments | NIRCam status | NIRCam comments | MIRI status | MIRI comments | NIRSpec status | NIRSpec comments | ||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| group_scale |
| The step is supossed to do nothing for NIRISS/SOSS (here, a group = 1 frame). Indeed, nothing changes when running this step, except for the length of the ASDF element in the HDU list object, which is normal. |
| N/A |
| |||||||||||||||||
| dq_init |
| This step correctly initializes the data-quality flags, as it is supposed to do, according to the reference mask in CRDS. |
|
|
| (high-level test) |
| ||||||||||||||||||
| saturation |
| This step does what is expected to do: it captures saturated pixels and flags them in the GROUPDQ masks. The simulations used for this validation had saturated pixels and they were correctly identified (flagged) by the pipeline. |

| superbias |
| Tested my own bias substraction using reference files and got exact same results. |
| N/A |
| |||||||||||||||||||||
| reset | N/A | N/A |
| This was tested on a TSO imaging file separately since this step does not currently run by default. The test passed with no issues. | N/A | |||||||||||||||||||||
| linearity |
| Tested linearity correction using reference files and got exact same results. |

| rscd | N/A | N/A |
| N/A | ||||||||||||||||||||||
| dark_current |
| Dark frames perform expected corrections on the data. |
|
|
| |||||||||||||||||||||
| refpix |
|
|
| Currently, does not do anything to NIRISS/SOSS simulations, as reference pixels there are set to zero. When injecting a fake strain of reference pixels got results I still don't understand (see below). |
|
|
| skipped for MIRI subarray data so only needs testing for FULL array imaging TSOs. this step is sufficiently tested in unit tests. |
| ||||||||||||||||||||||||
| jump |
| Step produced no errors. Manually introduced jumps were detected. |
|
|
| |||||||||||||||||||||
| ramp_fitting |
| *rateints files show small spikes that do not |
| show on my own |
| ramps, even when being careful with GROUPSDQ. |
| produced rateints with 7.5 and independent linear fits; substantial difference in a subset of data. |

| extract_1d |
| This step currently extracts the whole subarray as a spectrum, which produced order overlap, which makes this step produce an unusable product for science. An algorithm is in development for this step. For details, see
