astropy.units.core.UnitTypeError: Can only apply 'log10' function to dimensionless quantities

[3fon3fonov]

Jorge hi,

I can no longer run tpfplotter because of the error below. I tried on two different machines, same thing.

I am using python 3.8 & astropy==5.1

`WARNING: AstropyDeprecationWarning: The update_default_config function is deprecated and may be removed in a future version. [astroquery._astropy_init]

During handling of the above exception, another exception occurred:

The latest version of tpfplotter works smoothly for this target. I can run it without problems. Could you please update your tpfplotter to the latest version (in Github) and run it again? Let me know if the problem continues.

I just made a fresh git clone and I still have the problem.....

I just updated the code to make it compatible with Astropy latest version. The change does not affect previous versions of Astropy. Could you please check it now works? Thanks.

[3fon3fonov]

the error now is:

INFO: Query finished. [astroquery.utils.tap.core] --> Target found in the CTL!

Trifon, I made some changes to the code in the past weeks. Would you mind testing it with your python and module versions? Thanks.
