Baseline Fit Script (.bfScript) File
The baseline fit script (.bfScript) file specifies the targets tothe used in the baseline modeling calculations, and containes therelevant astrometry on each of these targets. In production this fileis automatically generated from a wide-band summary(.sum) file. The following are two exampleentries from a PTI bfScript file (this one taken from the file99138.bfScript) :

Each entry consists of one or more comment lines (prefixed withthe pound symbol '#') containing the target name and possiblyadditional information from the Hipparcos catalog.
Then there is an uncommented line of space-delimited values withdescriptions as follows:
| field# | content | comments |
|---|---|---|
| | target | Target designation (string) |
| | RA | h m s (J2000) |
| | Dec | d m s (J2000) |
| | RA and dec proper motion | RA and dec proper motion (arcsec/yr) |
| | parallax | Parallax (arcsec) |
| | V | V magnitude (optional) |
| | K | K magnitude (optional) |
| | Sp Type | Target spectral type (optional) |
| | Comments | Additional comments (optional) |
