| Column Label | Meaning |
| Measurement (ID) | A unique identifier for the measurement of which this bore data is part. |
| Reference |
What the length in the following columns to which is measured in relation; It can be the top of the joint, the bottom of the joint or even a tone hole or the end of a tenon. |
|
Maximum Length |
When a particular distance between the sides of the bore are taken in an elliptical bore, there will be two lengths that that distance falls. This is the longest of those distances. |
|
Minimum Length |
When a particular distance between the sides of the bore are taken in an elliptical bore, there will be two lengths that that distance falls. This is the shortest of those distances. |
|
Length cross grain (x) |
When a particular distance between the sides of the bore are taken in an elliptical bore, there will be two lengths that that distance falls. If the plane of the distance between the sides is recorded, this is the length when the diameter is taken in the plane of the centers of the tone hole axes. |
|
Length cross grain (y) |
When a particular distance between the sides of the bore are taken in an elliptical bore, there will be two lengths that that distance falls. If the plane of the distance between the sides is recorded, this is the length when the diameter is taken in the plane of the cross section of the tone holes. |
|
Diameter cross grain at (x) |
In an elliptical bore, the major and minor axes of two ellipses are given. This is the diameter of the bore at the lengths given above. It is also the major axis of the bore ellipse at the Length (x). |
|
Diameter with grain at (x) |
In an elliptical bore, the major and minor axes of two ellipses are given. This is the minor axis of the bore ellipse at the Length (x). See Note on ellipse calculations. |
|
Diameter cross grain at (y) |
In an elliptical bore, the major and minor axes of two ellipses are given. This is the major axis of the bore ellipse at the Length (y). See Note on ellipse calculations. |
|
Diameter with grain at (y) |
In an elliptical bore, the major and minor axes of two ellipses are given. This is the minor axis of the bore ellipse at the Length (y). See Note on ellipse calculations. |
|
Original Diam. at x (est.) |
Hypothetically, bore shrinkage can be calculated and the diameter of the original bore estimated. According to Karp [1978], The algorithm is given by the major axis plus This is the diameter estimate for length (x). |
|
Original Diam. at y (est.) |
Hypothetically, bore shrinkage can be calculated and the diameter of the original bore estimated. According to Karp [1978], The algorithm is given by the major axis plus This is the diameter estimate for length (y). |
