Actually Leo used a beta version of the new PPASINP.  That beta seems to be
fine, so it's now no longer a beta and can be downloaded from my website at


PPASINP V2.0 is a Windows program that takes your raw stopwatch readings of
satellites and converts them into the standard PPAS format.  Changes from V1.0

  - Now supports the Determination of Rotation Axis Project (DRA) format. 
  - DRA-style timings of every flash can be input in the DRA form, and the
user has 
    the option of creating DRA-format output, exporting the results to
average flash 
    period PPAS-format, or both. 
  - Calculation of start or end of flash period observations can now be made
from a 
    time synchronization 'mark.' Calculation of times relative to date and
time of 
    synchronization are rigorously converted to Julian date and time, so the
users need 
    not worry about pre- and post-midnight, change of year, year 2000, etc.
  - Recognizing that some users may be using Windows 3.1 with relatively
small amounts 
    of RAM, the coding was changed to use memory more sparingly.

I want to express my thanks to Leo Barhorst for agreeing to test the beta.
He was very patient, even after enduring four or five different builds of
the beta!

Please note that PPASINP is strictly a data-input interface.  If you would
like to
analyze groups of PPAS data, including plotting graphs of flash behavior
versus time,
then the program of choice is SatFlash v6.2 by Jean De Weerdt and Bart De
That program is available at the Oxford FTP site.

Hope you find the program useful and, as always, I welcome your comments.
