Associate LRS slitless observation with dedicated background.

[stscijgbot-jp]

Issue JP-3754 was created on JIRA by Greg Sloan:

Observers are advised to obtain a dedicated background for LRS slitless (TSO) spectroscopy, and can link the background and science observation in the APT. However, the pipeline by default will not associate the two observations, and thus will not use the dedicated observation to subtract the background. Users can run the pipeline manually and subtract a background, but the pipeline should be able to recognize the existence of a dedicated background and subtract it automatically.

Comment by Tyler Pauly on JIRA:

Hi Greg, do you have an example program that has utilized this option? Bonus points if the program has been executed.

Comment by Ian Wong on JIRA:

From a cursory look through the pipeline code, all spectroscopic TSO observations appear to be assigned the Asn_Lv2SpecTSO association rule set, which does not currently allow for non-science exposures to be added.

Could this rule be updated to allow for linked background exposures (in an analogous way to how it is handled in other observing modes)?

Comment by Ian Wong on JIRA:

Tyler Pauly see, for example, PID 4496 Obs 4, which is paired with the dedicated background observation Obs 5

Comment by Tyler Pauly on JIRA:

Thanks Ian! That should be sufficient test data for us to get a solution in order.

Comment by Greg Sloan on JIRA:

Ian should get the bonus points. All of PID 4496 has been executed.
