  The Liquids Reflectometer at Oak Ridge National Laboratory provides neutron
reflectivity capability for an average of about 30 experiments each year. In
recent years, there has been a large effort to streamline the data processing
and analysis for the instrument. While much of the data reduction can be
automated, data analysis remains something that needs to be done by scientists.
For this purpose, we present a reflectivity fitting web interface that captures
the process of setting up and executing fits while reducing the need for
installing software or writing Python scripts.
