Subsets

Subsets are different mutations of the dataset that you can create, filter, visualize and download. You can create as many Subsets as you like, and perform a variety of filtering options

Filtering#

Filtering uses a combination of:

  • Expressions: a custom filter expression to apply
  • Dataset: the stellar parameters pipeline used.
  • Targeting Filters: specific groups of sdss5 targets from different programs, mappers, or targeting cartons
  • Quick Flags: some simple flags for users. We default to having purely non-flagged data shown to users.
  • Crossmatch: specific identifiers to filter down to.
Dataset#

Within SDSS-5, multiple stellar parameters pipelines are used. For a valid analysis, one must choose a specific pipeline output to use for analysis.

By default, we use the best parameters, as described here TODO.

Downloading#

You can download your subset by clicking on the button in the bottom left of the Subset card.

Note that plot selections are not included in your download outputs.
