Fwd: [find_orb] Find_Orb only using three rows of data to generate ephemeris

Hi Bill,

Any advance on this? Sorry for pushing but the student has a rapidly approaching deadline.

Cheers,

Simon

Hi Bill, 

This is some data that I took a few years ago that a third year student is currently using. 

Cheers, 

Simon

Hi Simon, 

Hmmm... would you mind sending me the data? 

Find_Orb is, generally speaking, quite forgiving of oddities 
in the input data. MPC is not. If your observations do not match 
the format specification given at 

https://www.minorplanetcenter.net/iau/info/OpticalObs.html 

right down to the smallest details, they'll reject your data. 
Similarly, with the new ADES format, everything has to be Just 
Right for MPC to be able to handle your data. 

I found out early on that plenty of Find_Orb users would omit 
extra spaces or have extra data at the end of a line, and made the 
program such that it could usually figure things out. But it 
doesn't always do so, and I think this is one of those times. 
But without seeing the data, I can't say for sure.

When removing the top three rows it then randomly chooses three other rows to use for the calculation. Is there an easy solution for it to use all the data?
