To install the giants pipeline:
!git clone https://github.com/nksaunders/giants.git
!cd giants; pip install .To produce a de-trended light curve and a transit-search summary plot:
import giants
target = giants.Target(ticid=176956893)
target.fetch_and_clean_data(sectors=[1,2])
target.create_summary_plot()By default, this will query MAST and use all available sectors to produce a light curve (this can take a few minutes for some targets!). If you would like to specify which sectors to use, pass in a list of sectors numbers to the fetch_and_clean_data function, as shown above.
This will produce the following output:
You can also save the light curve for future use when producing the summary plot by passing in the save_data=True argument to create_summary_plot.
