Goals: explore the Rubin photometric reference data provided, and understand some of the details, such as the limiting depth, the photometric uncertainties.
If you have run the installation, you should have a directory called macss/data off you your home directory. It contains some data we will be using.
Open the notebook nb/Project_Part2.ipynb to find a notebook you can work on this second part of the project in.
Specifics: I have provided you with some prepared photometric reference data, which includes cross-matched objects with known redshifts. You will want to:
If you want to see what things should look like, you can have a look:
in the notebook 01_ExploreDESIFilters.ipynb to how the magnitudes as measured by Rubin compare with data from a different observatory.
in the notebook 02_ExploreInputs.ipynb to see examples how the magnitudes and colors vary with redshift.
in the notebook 03_LimitingMags.ipynb to see the effect of the cuts on the depth of the objects in the catalog.
in the notebook 04_CosmoRef.ipynb to see other ways the cosmology (and in particular the expansion of the universe) affect the data we are trying to use to estimate redshifts.
