ASTCLONE.BAS ... By Aldo Vitagliano, April 2019 Includes the source code and a sample of input file. This utility builds a SOLEX .SLX file of any number of "clones" of a given minor planet whose equinoctial elements and covariance table in ASCII format has been downloaded from the NeoDys or AstDys sites (below is a link to such table for asteroid (99942) Apophis). https://newton.spacedys.com/~neodys2/epoch//99942.eq1 The ASCII table must be saved to a file stored in the working directory of the program. The program can be unzipped and run in any folder, provided its input file(s) are stored in the same folder, and its output file(s) go to the same folder. The only important care is that the input file must stay in the same format as found in the AstDys/NeoDys databases. A sample is enclosed (Apophis.cov). The program prompts for three entries, that must be typed from keyboard: 1) The input filename 2) The output SLX filename (must be entered without the SLX estension) 3) The number of clones to be generated. The output SLX file can then be imported by SOLEX as such.
