Annuli not working

[wschoenell]

When I run lemon annuli I get the error below. It tries to run lemon diffphot with a --output option when this option does not exists. I am able to fix this problem doing this: https://github.com/vterron/lemon/compare/vterron:2585cd0...wschoenell:f8b9402

lemon annuli: error: no such option: --output

My apologies: annuli stopped working long ago and should have already been removed. It was never a good idea and the whole concept of automatically determining the optimal parameters for aperture photometry was merely more than a rudimentary proof-of-concept — if only it were that easy.

I'm opening an issue as a reminder to exterminate the command as soon as I resume the development of the pipeline.

[wschoenell]

Thanks! Is there another module with proof of concept status that should be not used?

[vterron]

No, that's the only one! Although if you take a look at the list of commands you can see that they are divided into two categories: essential and auxiliary. The latter are scripts that have proved useful in the past and may be of help to other people, but that do not necessarily belong in a pipeline for differential photometry whose sole purpose is to generate light curves:

vterron@iaa:~$ lemon
usage: lemon [--help] [--version] [--update] COMMAND [ARGS]

The essential commands are:
   astrometry   Calibrate the images astrometrically
   mosaic       Assemble the images into a mosaic
   photometry   Perform aperture photometry
   diffphot     Generate light curves
   juicer       LEMONdB browser and variability analyzer

The auxiliary, not-always-necessary commands are:
   import       Group the images of an observing campaign
   seeing       Discard images with bad seeing or elongated
   annuli       Find optimal parameters for photometry

See 'lemon COMMAND' for more information on a specific command.

It might be the case that these auxiliary commands will change or be removed in the future, but the essential ones are expected and pretty much guaranteed to remain the same.

Thanks @vterron!
