H-band light curves of Milky Way Cepheids via Difference Imaging
  We present H-band light curves of Milky Way Classical Cepheids observed as
part of the DEHVILS survey with the Wide-Field Infrared Camera on the United
Kingdom InfraRed Telescope. Due to the crowded nature of these fields caused by
defocusing the Camera, we performed difference-imaging photometry by modifying
a pipeline originally developed to analyze images from the Transiting Exoplanet
Survey Satellite. We achieved a photometric precision in line with expectations
from photon statistics, reaching 0.01 mag for 8 <= H <= 11 mag. We used the
resulting Cepheid light curves to derive corrections to "mean light" for
random-phase Hubble Space Telescope observations in F160W. We find good
agreement with previous phase corrections based on VI light curves from the
literature, with a mean difference of -1 +/- 6 millimag.
