Accessing processed visit images

how would one go about accessing individual visit images, in addition to the coadds?


Those will have a “calexp” dataset type. There were some calexp examples in notebook 3. You can call butler.registry.queryDatasets looking for calexp files in a particular filter or simulated date range.

Hi, thanks for the reply. I installed the LSST stack and am trying to run notebook 3.
But when instantiating Butler I get “botocore.exceptions.NoCredentialsError: Unable to locate credentials”.

Quick search through the forums and Butler documentation doesn’t give much.


Hi @petarz, if you’re using the DP0 tutorial notebooks from this GitHub repository, note that they will only work on the Rubin Science Platform deployed at the Interim Data Facility for Data Preview 0, which is currently only available to a limited number of community participants.

The first round of applications for participating in DP0 is already complete (more info here), but there will be another opportunity in early 2022.

Ok, makes sense. Thanks, Melissa
