Work Plan

To Do

• See if the limited precision in the time in Weryk's code might be responsible for the errors during the Apophis encounter.
• Find and describe the term that has the larger error.
• Make a couple of example notebooks and codes.
• Package the examples.
• Incorporate tests into pypi package.
• Finish documentation on github and readthedocs. (readthedocs requires that the github site be public.)
• Ask Hanno about assist_free issue.
• Implement changes to needed to fully use Weryk's updated ephemeris code.
• Ask Hanno about the symbolic link issue.
• Benchmark ASSIST against JPL.
• Arya reviews tests of terms and variational equations.
• Investigate the origin of the quadratic error growth.
• Matt finalizes python wrapper
• Incorporate a caching system into the all_ephem routine.

Postponed

• Move xo, yo, zo values to assist struct
• Move output file pointers to assist struct
• Matt writes a version of store_function that stores the chebyshev coefficients
• Matt writes a routine that reads the coefficients and computes positions/velocities
• Matt adds more non-grav terms
• Matt works on satellite orbit fitting
• Matt recovers 2020 CD3 orbit fit work

Finished

• Review the Scholar Studies budget, find out how quickly the money needs to be spent. DONE
• Arya plugs in the higher order terms. DONE
• Arya plugs in the variational equations. DONE
• Matt recovers tests of variational equations. DONE
• Plan the next visit -- in 4-6 weeks. DONE
• Clean up and document the higher order and variational code in assist.c DONE
• Need to get constants and parameters from the DE441 file, when possible DONE
• Add means of passing in non-grav parameters. DONE
• Add means of adjusting the non-grav parameters. DONE
• Develop and test code for variations of non-grav terms. DONE
• Circulate draft. DONE
• Ask for help with pypi installation. DONE
