Size Distribution Fitting (lognormal) - Wdie-Range Particle Sizer (WPS) Data Processing

This igor procedure is to handle the airborne particle size distribution data measured using Wdie-Range Particle Sizer (WPS), since the original software provided along with the instrument is not very user-friendly.

Starting with a neatly organized panel, all functions are simple and straightforward:
- Load raw data with a single click;
- Automatically obtain major parameters (RH, temperature) and calculate the hourly average; (daily or monthly average will be added in future release)
- Graphing (size distribution, color-coded by number conc.);
- Fit the size distribution into three log-normal modes (aitken/accumulation/coarse), using Lavenburg-Marquardt method.

Ver 2.0 release on 15 Mar 2012.
- dS/dlogDp and dV/dlogDp now included.

Ver 1.5 released on 1 Mar 2012. Major updates include:
- Diffusion loss correction is considered, based on temperature, pressure and a few user-supplied parameters. Using method described in Hinds (1999).
- Some minor bugs fixed.
