I’m trying to get an image of a specific star, and I have its coordinates. I was able to first locate it using DP1 Catalogs, but now I need to be able to get a better image, which I will use to simulate the same star in PhoSim. I’m really struggling to figure out how to do this, as this is my first time using the portal. Each time I think I have something, the estimated run time is 24 hours, which is a lot of time just to see if what I did was correct in the first place. So what am I doing wrong?
Hi @CamR . Thanks for your post. Could you share more details about the code that produces the estimated run time, and what aspect of the RSP you are using?
Are you wanting this tutorial? 102.2. Query for images with SIAv2 — DP1
SIA is what you need to do a RA/Dec search for an image and then view the image. You can also trigger a cutout request for that image.

I will try this, thank you!
I was looking at the “Job Information” button in the Job Monitor while it was processing. Could you expand more on what you mean by the “aspect” of RSP? I don’t quite have all of the terminology yet; I’m trying to figure it out as I go.
Hi @CamR,
By “aspect”, it was which of the RSP’s three aspects, Portal, Notebook, or API, you were using: https://rsp.lsst.io/guides/index.html#aspects.
It sounds like you were at first using the Portal Aspect (because that’s where the Job Monitor tab is). And Tim linked you to a Portal tutorial for the SIA service.
However, it sounds like you are only interested in images that contain your star, and that SIA tutorial will return all images that overlap a region on the sky. I’d also recommend Portal tutorial 102.3. Query for images with ObsTAP — DP1. In Step 6 replace the coordinates with your star coordinates. And skip Step 7, “set the timing”, in order to return all DP1 images that overlap your star (because I’m not sure your star was observed in the time range used by that tutorial).
Let us know how that works? (And if it works well, mark this topic as solved?)
