+Imaging data were collected with the Sinistro imagers on the LCOGT 1m 
+telescope network between 2022-07-31 and 2023-01-27 UTC for measuring 
+lightcurves of the Didymos system. In total there are 47

 Data Set Overview
 =================
 
-The photometry of Didymos is measured from the calibrated frames (see
-date_lcogtcal collection) using the NEOexchange or PHOTOMETRYPIPELINE
-pipelines. Both perform source detection in the images using SExtractor
-(Bertin, E and Arnouts, S. 1996. SExtractor: Software for source
-extraction. A&AS, 117, 393), astrometric fits to the detected sources
-based on the known positions of Gaia DR2 stars in the field using SCAMP
-(Bertin, E. 2006.  Automatic Astrometric and Photometric Calibration
-with SCAMP. ASPC, 351,112), photometrically calibrates the zero point
-of the images based on the measured flux of field stars that have known
-catalog magnitudes (typically from eithe the PanSTARRS or Gaia-DR2
-catalogs), and then using these astrometric and photometric solutions
-derives a calibrated magnitude for Didymos. The photometry tables
-included in this collection are the output of these pipelines.
