     309Developed initial hardware requirement estimates for DayMOPS using OOrb rather than JPL. 
     310 
     311Worked with Jacek and Lynne Jones to help estimate DayMOPS database requirements. 
     312 
     313Worked closely with Mikael Granvik to build, test and validate f2py-based wrappers to OOrb based on our needs.  These will hopefully replace or augment existing wrappers to OOrb, which have been found to cause occasional mysterious memory errors. 
     314 
     315Ran a series of benchmarks on various configurations of nightly ephemeris stored in a database.   
     316 
     317Used a sample of PS-MOPS asteroid catalog to find amount of error generated by the nightly linear approximation of NEO paths compared with hourly true ephemeris. 
     318 
     319Using knowledge from above database experiments, discussed and planned (with Lynne Jones and Simon Krughoff) a new asteroid ephemeris generation utility to be used for generating MOPS input catalogs and asteroid locations for the ImSim catalogs.  Unlike PanSTARRS tools, ours will keep nightly ephemeris in a database from simulation to simulation, avoiding the need to calculate new ephemerides.  This code is planned to serve as the basis for a slightly cleaner, OOrb-based NightMOPS as well.
