Selecting subsets in Glue

[smallstudent2021]

Would it be possible to implement a feature in Glue that allows the selection of subsets based on user input of X and Y values?

Do you mean adding this to the user interface (GUI)? Currently you can do this most easily from the built-in terminal. For instance, taking the example from the data tutorial you can do something like this to define very specific ranges:

>>> dc
DataCollection (2 data sets)
      0: w5[PRIMARY]
      1: w5_psc
>>> catalog = dc[1]
>>> hmag = catalog.id['Hmag']
>>> mid_mag = (hmag > 10) & (hmag < 15)
>>> dc.new_subset_group('between_10_15', mid_mag)

I think the general philosophy is that there are some selections that are best to make with the subset tools, and some (i.e. if you care about exact values) that are best to do in code at the terminal.

Yes, that's what I mean. I see what you mean, it's better to implement it in terminal code. But to someone unfamiliar with python and code, this may seem unfriendly.

Thank you for your reply
