TypeError: 'float' object is not callable

For a Aperture sum, with radius region_size g Return curve of growth plot r Return the radial profile plot

I am getting errors when I do the three above utilities. The other utilities in imexam seem to work just fine. I'm using python 3 and a jupyter notebook. I've displayed an image reduced with the Gemin DRAGONS pacakge.

import imexam

viewer=imexam.connect() # startup a new DS9 window

viewer.load_fits('N20191112S0096_sourcesDetected.fits') # load a fits image into it

viewer.imexam()

When I type r:

Current image /Users/mschwamb/Research/playground/N20191112S0096_sourcesDetected.fits xc=1419.887294 yc=839.575413

I'm not sure what's the issue or how to fix it. I'm happy to share the image if that would be helpful for debugging.

I have the same bug in the the profile or aperture photometry tools, using python=3.6 or 3.7. I am also using anaconda (on mac). Shame, this seemed like a good replacement for that IRAF tool!

Also trying with the development version produces the same errors: (pip install git+https://github.com/spacetelescope/imexam.git)

[hjmcc]

It seems there was a change to the photutils.aperture API in version 0.7 (.area() was switched to an attribute and not a method). Switching back to version 0.6 doesn't fix the problem. Changing the code to .area from .area() doesn't work for me unfortunately (another bug pops up).

[sosey]

sorry, I've been swamped with other work lately. I'm sure this can be fixed, I'll try and take a look soon, but thank you for reporting the issues.

[hjmcc]

No worries, thanks for making this tool available, it is very helpful !

For info, in fact switching to .area from .area() fixes two of the three aperture sum tasks, 'a' and 'g', the error now given with 'r' is

[sosey]

try the code from this PR: https://github.com/spacetelescope/imexam/pull/195 and let me know if it's working for you. I tried it with 0.6.dev28+g5fc8f449 and 0.7.1

[mschwamb]

I updated with pip install --upgrade imexam and tried again and still having the same issue.

[pjpessi]

Hi, I get this same error when in python 3.6.10 I run viewer.imexam() and press a. It says you are 'calling' a float, so maybe there are () instead of [ ] somewhere?

[patkel]

Hi, this problem can be fixed by removing the parentheses after area. i.e., area() -> area

[sosey]

This code was fixed in #195 and is on the master branch, but I haven't had a chance to make a formal release, so there isn't a new pip release. I'll try and get to a release soon, but until then you can install straight from the repo:

pip uninstall imexam pip install git+https://github.com/spacetelescope/imexam.git

[pjpessi]

Installing imexam with pip somehow breaks my xpa installation. I wrote the error below. It would be nice to have this version available to install with conda. I guess I will wait until then.
