HLPWWW (Version 9.0a) JESS copyright (C) 1985-2025 Licensee : Webmaster, Murdoch University, Australia Welcome. Sunday, 7-Dec-25 22:53 The ESTA program suite provides a wide range of facilities for equilibrium simulation and titration analysis. Consult the index for specific details on the following programs. ESTA0 - Gran function analysis ESTA1 - Titration simulation and pointwise analysis ESTA2B - Global optimisation of titration parameters ESTA3B - Monte Carlo error analysis ESTA7 - Error imposition module The ESTA programs were developed prior to JESS coding protocols (it was our experience with ESTA that proved the need and pointed the way for many of the approaches we have taken in developing JESS.) For this reason the ESTA programs do not fully conform with the rest of JESS and sometimes behave idiosyncratically. However, the ESTA code is now very well tested and, thus, we think reliable. It is included in the JESS package because we find that it is still very useful. It is appropriate to use ESTA for simulating and analysing the potentiometric properties of well controlled laboratory solutions. The key is for you to try first in an empty folder by copying one or more of the *.EST files from ..GLOBAL\DEVTST as examples. With a properly named file, you simply enter, for instance, 'ESTA1 filename' (no quotes and without file extension). You can get the output sent to a file (cf displayed at VDU), necessary since ESTA utilised the full 132 characters then available on line printers! Finally, you need to prepare your own input file(s) following the examples as templates and the instructions in the maual.
