The simulated LLR data are round-trip travel times between Earth station and lunar retro-reflector. And the simulated DLLR data are range differences between the ranges measured by the same station to different lunar reflectors within a short time interval. For the simulated DLLR data, the measurement time for the second reflector minus the measurement time for the first reflector is 1.5 minutes. The folders "ReflectorBaselines", "TimespanStations" and "NewReflectors" contain the simulated LLR and DLLR data used for different analysis cases. The type of the simulated data (LLR or DLLR) and the corresponding case are shown in the name of the simulated data files. Below are the contents of the different columns of the simulated LLR and DLLR data. The columns of the simulated DLLR data contain the following information: 1. station name 2. measurment time t1 for reflector 1 [JD-2440000.0] 3. reflector 1 name 4. reflector 2 name 5. range difference [km] 6. accuracy [nm] 7. temperature [Celsius degree] 8. pressure [hPa] 9. wavelength [nm] 10. humidity [%] The columns of the simulated LLR data contain the following information: 1. station name 2. measurement time for a reflector [JD-2440000.0] 3. reflector name 4. round-trip travel time [s] 5. accuracy [ns] 6. temperature [Celsius degree] 7. pressure [hPa] 8. wavelength [nm] 9. humidity [%] More details about the data and their analysis can be found in: 1.
