One of the main tasks of the TSO WG on FY2020 is to perform testing of the steps made by the JWST Calibration Pipeline for TSO-like data. This tracking sheet contains all the information regarding pipeline testing by the members of the TSO WG. Nestor Espinoza and Sarah Kendrew will be populating this page heavily in the weeks of July 20 and 27, 2020, for NIRISS and MIRI TSO testing, respectively. Nikolay Nikolov and Tony Keyes will be populating at their own pace for NIRCam and NIRSpec, respectively.

General guidelines for Pipeline Testing

  1. Please, test every step identified below. If for some reason you don't have time to test a step, let Nestor Espinoza and Sarah Kendrew know.
  2. Use the comments in the tables to post brief comments about the status of that testing step (think of it as a quick overview for others to know what is going on). For extended commentary, or details on how you performed the testing, use the text below the tables.
  3. If a bug is found, please report it in Jira as a "Bug" Jira ticket. Please copy the links to those tickets in the table below under the comments.
  4. For algorithm improvements/enhancements, please file an "Improvement" Jira ticket. Please copy the links to those tickets in the table below under the comments.

 In general, if bugs are found, the best would be to discuss them first in one of our meetings before going ahead and submitting them (unless this is high-priority, in which case we could schedule a special meeting for this). This is left at the discretion of each TSO WG member.

General comments

Before jumping to read the below table, some important comments to keep in mind while reading them:

Stage 1: Detector Processing TSO testing

Pipeline stepNIRISS statusNIRISS commentsNIRCam statusNIRCam commentsMIRI statusMIRI commentsNIRSpec statusNIRSpec 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. However, still not clear what the PIXELDQ mask is reporting. GROUPDQ masks make sense with respect to the reference file bad pixel mask.




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.

jump

Step produced no errors. Manually introduced jumps were detected.




ramp_fitting

*rateints files show spikes not seen with my own ramp fits, and do not report timestamps. This has been identified as an awesimsoss header bug.

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 .
