Work Plan

To Do

• Find and describe the term that has the larger error.
• Finish documentation on github and readthedocs. (readthedocs requires that the github site be public.)
• Benchmark ASSIST against JPL and other codes.

Postponed

• 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
• Ask Hanno about the symbolic link issue. RESOLVED
• Matt finalizes python wrapper. Hanno
• Implement changes to needed to fully use Weryk's updated ephemeris code. DONE
• See if the limited precision in the time in Weryk's code might be responsible for the errors during the Apophis encounter. DONE
• Investigate the origin of the quadratic error growth. DONE
• Make a couple of example notebooks and codes. Hanno. DONE
• Package the examples. Hanno. DONE
• Incorporate tests into pypi package. DONE
• Ask Hanno about assist_free issue. Hanno. DONE
• Arya reviews tests of terms and variational equations. DONE
• Incorporate a caching system into the all_ephem routine. Hanno. DONE
• Move xo, yo, zo values to assist struct Hanno. DONE
• Move output file pointers to assist struct Hanno. DONE
• Matt writes a version of store_function that stores the chebyshev coefficients Hanno. DONE
