== Sample and Data File Convention ==
An acrylic sample convention is composed of 4 digits.
{{{
label-batch-panel-piece
}}}

Each raw data file is composed of 6 digits.
The first digit indicate the type of measurement.
The following 4 digits indicate which acrylic sample is adopted.
The last digit indicates the number of measurement.
{{{
type-label-batch-panel-piece-measurement
}}}

A typical convention of raw data look like:
{{{
T-B321-5
}}}
This means it's the fifth transmission measurement of the sample used for barrel of some IAV, and
it's one piece of a panel ( called number 2) of batch 3.

|| Label || Description ||
|| B || The acrylic sample is used for the barrel of IAV ||
|| L || The acrylic sample is used for the lids of IAV ||
|| R || The acrylic sample is used for the ribs and flanges of IAV ||
|| O || The acrylic sample is not used for the above parts of IAV ||

Nakano uses the same acrylic panels for the ribs and flanges of IAV#1 and IAV#2.
If not specified, the label "R" means the acrylic sample is used for both the ribs and flanges of IAV.

|| Measurement Type || Description || Details ||
|| T || Total transmission || PerkinElmer Lambda 650 spectrometer ||
|| R || Total reflection || PerkinElmer Lambda 650 spectrometer ||
|| D || Diffuse reflection || PerkinElmer Lambda 650 spectrometer ||
|| N || Index of refraction || doc:3499 ||
|| A || Absorption length || doc:3499 ||
|| O || Other kinds of measurement not mentioned above || ||

== Data format ==

=== Transmission/Reflection ===

A typical transmission/reflection spectrum looks like
{{{
800 92.4132 0.131976
799 92.446 0.118017
798 92.3688 0.09428
}}}

It means
|| wavelength(nm)  || transmission/reflection mean value (%) || RMS (%) ||


RMS is taken by the average of the value to repeat scanning spectrum three times,
then rotate the sample ~90 degree, and finally repeat scanning spectrum three times, again.

If no extra explanation, the optical spectrum of transmission/reflection follows this format.
For example,
source:IAV/material/optical/T-B112-1.dat

=== Attenuation Length ===

|| wavelength(nm) || Attenuation Length (mm) || + uncertainty (mm)  || - uncertainty (mm) ||

=== Index of Refraction ===

|| wavelength(nm) || index of refraction || uncertainty ||
