Cluster Difference Imaging Photometric Survey. I. Light Curves of Stars
  in Open Clusters from TESS Sectors 6 & 7
  The Transiting Exoplanet Survey Satellite (TESS) is providing precise
time-series photometry for most star clusters in the solar neighborhood. Using
the TESS images, we have begun a Cluster Difference Imaging Photometric Survey
(CDIPS), in which we are focusing both on stars that are candidate cluster
members, and on stars that show indications of youth. Our aims are to discover
giant transiting planets with known ages, and to provide light curves suitable
for studies in stellar astrophysics. For this work, we made 159,343 light
curves of candidate young stars, across 596 distinct clusters. Each light curve
represents between 20 and 25 days of observations of a star brighter than
$G_{\rm Rp}=16$, with 30-minute sampling. We describe the image subtraction and
time-series analysis techniques we used to create the light curves, which have
noise properties that agree with theoretical expectations. We also comment on
the possible utility of the light curve sample for studies of stellar rotation
evolution, and binary eccentricity damping. The light curves, which cover about
one sixth of the galactic plane, are available as a MAST High Level Science
Product at https://doi.org/10.17909/t9-ayd0-k727 .
