Occassionally, light curves provided by the TESS Science Processing Operations Center (SPOC) contain significant scatter, particularly during periods of less stable spacecraft pointing. Often the light curve quality can be significantly improved by picking a different, generally larger, aperture. The purpose of this code is to generate improved light curves when this situation occurs, primarily using methods from the lightkurve package. It first generates a new aperture mask, then calculates a new light curve from simple aperture photometry over this mask. Finally, it removes some instrumental noise using linear regression.
First change the class of the target pixel file to the sydsap_tpf class, then run tpf.sydsap():
from sydsap.sydsap import sydsap_tpf
tpf__class__ = sydsap_tpf
lc = tpf.sydsap()We invite anyone interested to use and modify this code under a GPL v3 license.
