# The data is given in the table below using commas (,) as the separator
# between columns. Numbers are denoted like 32.3, 0.043, and 3.45e3. Strings
# are denoted as "hello world" in double quotes. Header lines are prefixed
# with a pound symbol (#). Newlines are DOS/Windows style ('\r\n').

# The table of all of the particle types we used with their materials, forms,
# sizes, forms, and manufacturer information (including product number). The
# table and its headers follow immediately after the column descriptions
# 
# 0 : designation            : designation for the particle type in this data repository (string)
# 1 : material               : particle material (string)
# 2 : form                   : particle form, which can be powder or spheres (string)
# 3 : d_min (microns)        : particle minimum diameter in micrometers
# 4 : d_max (microns)        : particle maximum diameter in micrometers
# 5 : manufacturer           : manufacturer of the particles (string)
# 6 : product #              : product number for the particles (string)
# 7 : nominal size (microns) : manufacturer nominal size range of the particles in micrometers (string)
