MPCORB dat file

B. Hudgens Apr 19, 2003

The MPCORB.DAT file is presently over 187,000 lines of data. I there an easier way to edit out, say only the first lines above the first 50,000, and not have to use the entire massive .dat file. I have been using Guide for many years and still have a rather slow (450Mz) system. I am only concerned with visual asteroid observing and my current limit is about 15.5 mag. You can use the mag. filter to limit the display, but the entire .dat file is still being accessed.

I tried to edit out the above using TextPad and other similar word processors, but it is a real time consuming routine. Is there a better way to edit this massive file?

Thanks, Ben
