tesscentroidvetting 1.4.0

TESS Centroid Vetting

TESS centroid_vetting

Attempt to make a centroid vetting function graphically similar to the one used in the DV reports of TCE's produced by the TESS Science Processing Pipeline.
This centroid presentation allows to identify the source of the dips in a lightcurve, discarding eventual false positives and identifying possible sources of contamination.

Installation

Since version 1.2.0, a package is available at PyPi.
So, the simplest way of installing TESS-Centroid_Vetting is using pip:

pip install tesscentroidvetting

Dependencies:

• numpy
• matplotlib
• astropy
• astroquery
• scipy
• lightkurve
• ipywidgets - only needed if interact=True in show_transit_margins()

Usage

See the notebooks in Examples directory for usage.
