                   AnetHeaderProcessor

A file processor for calibrating FITS frames using astrometry.net.

It might provide calibration for "simple" cases out of the box. You will usually want to override some solver parameters. To do that, define class attributes sp_<parameter name>, where the parameters available are discussed in helpers.anet's docstring. sp_indices is one thing you will typically need to override.

To use SExtractor rather than anet's source extractor, override sexControl, to use an object filter (see anet.getWCSFieldsFor), override the objectFilter attribute.

To add additional fields, override _getHeader and call the parent class' _getHeader method. To change the way astrometry.net is called, override the _solveAnet method (it needs to return some result anet.of getWCSFieldsFor) and call _runAnet with your custom arguments for getWCSFieldsFor.
