everest - Command line access

The everest command accepts several options, which we list below.

ID	The target ID number (required)
-1	Plot the everest 1.0 de-trended light curve (K2 only)
-2	Plot the everest 2.0 de-trended light curve (default)
-a	Plot the target aperture/postage stamp
-c cadence	Cadence type (lc | sc). Default lc
-d	Show the everest 2.0 data validation summary
-f	Plot the k2sff light curve for the target (K2 only)
-h	Show the help message and exit
-m mission	The mission name (k2 | kepler | tess). Default k2
-n	Do not apply the CBV correction
-r	Plot the raw light curve
-s	Plot the k2sc light curve for the target (K2 only)

This tool implements most of the basic everest functionality. It automatically downloads light curves and data validation summaries from MAST and plots them with some customization. Below we show some examples. For other options and further customization, see the Python user interface section.

Everest 1

The -1 option brings up the light curve de-trended with version 1 of the pipeline:

Everest 2

The -2 option (default, if no flags are present) shows the light curve de-trended with the current version (2) of the pipeline:

If the -n flag is present, the code does not apply the CBV correction, resulting in a light curve with a bit more low-frequency residual systematics:

Other pipelines

Other supported pipelines can be plotted with the --pipeline_name flag, or with the abbreviated flags (i.e., -f for k2sff or -s for k2sc). Here’s the plot for everest 201367065 –k2sff:

Raw

The -r option brings up the raw light curve:

Data Validation Summary

See Data Validation Summary.

Aperture

Nothing too fancy. The -a flag plots the postage stamp with the aperture used to de-trend:

The plots show snapshots of the postage stamp at the beginning of the timeseries (start), the middle of the timeseries (mid) and the end of the timeseries (end). The final plot (hires) is a high resolution image of the target. For K2, this is taken from the Palomary Observatory Sky Survey.
