I. Disclaimer:

The National Institute of Standards and Technology (NIST) uses its best
efforts to deliver a high quality copy of the Database and to verify
that the data contained therein have been selected on the basis of
sound scientific judgement. However, NIST makes no warranties to that
effect, and NIST shall not be liable for any damage that may result
from errors or omissions in the Database.

II. Why you should use the Web:

   - Simple and convenient user interface
   - Downloading data in spreadsheet (array) format
   - Graphing
   - Including the default energies with user defined ones
   - Updated regularly

V. Setup for ESTAR:

1. Make a directory for ESTAR
2. Unzip the ESTAR zip into that directory

Note: PC users can skip step 3

3. Compile (and link) ESTAR.f, COMPOS.f, EDCONV.f, and CONVERT.f
4. Run the executable version of EDCONV (outputs: UEDAT)
5. Run the executable version of CONVERT (outputs: UCOMP)

To run the program, run ESTAR and follow command line instructions

VI. Running ESTAR:

1. Output Options
   a: Stopping powers, ranges and radiation yields, for standard energy
      grid only
   b: Stopping powers only, for user-selected energy grid

2. Material Selection
   a: Use predefined common material (see material.txt for a list of
      materials)(use COMPOS to view the compositional data for these
      materials)
   b: Enter your own material and its compositional data

3. Energy List
   a: Default list, 81 energies between 1 keV and 1000 MeV
   b: User-selected list stored in a file
      - First line contains the number of energies in the list
      - Subsequent lines contain energies in MeV separated by blanks
   c: User-selected list entered as prompted
