IN DECEMBER 2015 WE WERE INFORMED OF THE WFIRST SCIENCE INVESTIGATION TEAM SELECTIONS AND OF THE FUNDING FOR THE WIRST SCIENCE INVESTIGATION TEAMS. UNFORTUNATELY THE FUNDING FOR THE WFIRST EXOPLANET MICROLENSING PROGRAM WAS NOT SUFFICIENT TO DEVELOP ALL THE TOOLS NEEDED TO EXECUTE THIS PROGRAM. BECAUSE OF THIS THE PI SUBMITTED A REQUEST TO THE NASA PROGRAM OFFICER DR. DOMINIC BENFORD TO CHANGE THE FOCUS OF THIS WFIRST PREPARATORY SCIENCE GRANT AND DR. BENFORD APPROVED THIS REQUEST. THE NEW FOCUS INCLUDES THE DEVELOPMENT OF THE WFIRST EXOPLANET MICROLENSING SURVEY PHOTOMETRY/ASTROMETRY PIPELINE ALGORITHMS AND THE DEVELOPMENT OF ADVANCED LIGHT CURVE MODELING AND DATA ANALYSIS METHODS. IT ALSO INCLUDES THE STUDY OF MICROLENSING EVENTS LOCATED IN THE CANDIDATE WFIRST EXOPLANET MICROLENSING SURVEY FIELDS TO DETERMINE IF NEW DIFFICULTIES MIGHT ARISE WITH THE WFIRST EXOPLANET MASS MEASUREMENT METHODS DUE TO THE LOW LATITUDES OF THE WFIRST MICROLENSING FIELDS.
