Error when instantiating selection function object

[mitchellkarmen]

Hi,

I'm trying to use the TGAS selection function, and am using the following code to instantiate it:

tsf= gaia_tools.select.tgasSelect()

But I get the following error message:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

TypeError: numpy boolean subtract, the `-` operator, is deprecated, use the bitwise_xor, the `^` operator, or the logical_xor function instead.

If you could offer insight into what I'm doing wrong or what I need to do differently, I'd greatly appreciate it!

Apologies, this is syntax that used to be allowed in Python, but hasn't for a few years now and I keep having to fix this bug in all of my code! Should be fixed in master now.

Note that with Gaia DR2 out now for more than 2 years, I don't know how useful the TGAS (Gaia DR1) selection function is at this point...
