For DP0.2 will it be possible to access the RSP through TAP from an external site. E.g., directly running a TAP client (e.g., pyvo.dal.TAPService) from my laptop or NERSC?

Oh, it is “official”, then. For notebook steps 4+5, I found it simpler to do: cred = pyvo.auth.CredentialStore() cred.set_password("x-oauth-basic", token) tap = pyvo.dal.TAPService(tap_url, session=cred.get("ivo://ivoa.net/sso#BasicAA")) (and no need to import requests)

I am asking about the opposite direction of access from the following two posts, which were about accessing an external TAP service from the RSP: [image] Accessing External TAP Services from an RSP Jupyter Notebook Data Preview 0 Informational: At today’s (20…

For DP0.1, I was able to access the RSP TAP services using TOPCAT on my laptop; so I believe this will be the case. Let me revisit this question in full a little later today…

I get DALServiceError: 401 Client Error: Unauthorized for url: https://data.lsst.cloud/api/tap/sync When I try to do it from external to the RSP.

You will need to provide a token in some way (authorization header or as username/password) to access TAP from outside the RSP. See SQR-039: Discussion of authentication and authorization for Science Platform . As Douglas says, this works today (via https://data.lsst.cloud/auth/tokens/ ), but I’m no…

Thanks for the pointer to that SQR document, @ktl , I’ll try it out. @frossie Are there any performance limitations I should anticipate? Or, “How can I be a nice DP0 Delegate and not break things?”

Sorry for the delay. I had to dig into the code a bit… Anyway, @MelissaGraham pointed me to this useful piece Rubin DP0 Delegate documenation: https://data.lsst.cloud/api-aspect . Once you have your data.lsst.cloud TAP service token, you can either use it other TAP access services. I will give …

Thanks, all! I tried @ktl 's solution and it works perfectly.

Thanks, @DouglasLTucker I appreciate the gory details for exactly the purpose of providing a good detailed answer for people searching this in the future (which will likely include us). I wasn’t familiar with using requests and appreciate learning about building the auth by specifying what to do …

@mwv I would prefer @ktl ’s more concise recipe be propagated. It’s the result of some recent work on improving Python interfaces to authenticated IVOA services, and it’ll be more robust than enumerating specific endpoints (which could very well change over time - they are not required by the standa…

Yep. Here’s what I wrote up and circulated to DESC as a simple example test of NOIRLab and RSP TAP services. test_rsp_tap_service.py (1.5 KB)

Will there be external TAP access to RSP DP0.2 tables?
