LEGEND:  The tables below defines the properties represented in the Quality Summary, updated each week during the crop season.

WHITE GRADES*
MID+	Percent of bales receiving grades of 11, 21, or 31.
SLM	Percent of bales receiving a grade of 41.
LM-	Percent of bales receiving grades of 51, 61, or 71.
TOT	Total percentage of bales classified as “White.”

LIGHT SPOTTED GRADES*
MID+	Percent of bales receiving grades of 12, 22, or 32.
SLM	Percent of bales receiving a grade of 42.
LM-	Percent of bales receiving grades of 52 or 62.
TOT	Total percentage of bales classified as “Light Spotted.”

OTHER GRADES	Percentage of bales classed as “Spotted,” “Tinged,” “Yellow- Stained,” or “Below Grade.”
BARKY GRADES	Percentage of bales from each classing office containing bark.

Fiber Properties
MIC unit	Micronaire (MIC) is a measure of the air permeabilty of compressed cotton fibers.  It is often used as an indication of fiber fineness and maturity. Micronaire readings of 37-42 are premium, 35-36 or 43-49 are base, and  34-and-under or 50-and-higher are discount.   Micronaire is measured using the HVI.
LEN 32/in	Staple Length is the average of the longest 50% of the fibers (Upper Half Mean Length).  It is measured in 100th's and in 32's of an inch.  For the conversion chart, see the USDA's Classification of Cotton. Length is measured by the HVI.
LUI (%)	Length Uniformity Index (LUI) is the ratio (given as a percent) of the average length, to the upper-half-mean-length (see adjacent description). LUI is an indicator of how fibers will perform in the spinning of yarn.  LUI is measured using the HVI.
STR g/t	Strength (STR) reports the force, in grams, required to break a bundle of fibers one tex unit in size.  A tex unit is the weight in grams of 1,000 meters of fiber.  For more information, see the USDA's Classification of Cotton. Strength is measured on the HVI.
TRASH (%)	Trash content is a measure of the non-lint particles (like leaf, bark) in the cotton.  It is given as the percentage of surface area occupied by trash when a cotton sample is scanned by a camera.  Trash is also measured by the HVI.
MAT RATIO	Maturity Ratio (MAT) is the relative amount of cellulose in the fiber cross section. Higher values generally indicate more  mature cotton.  This ratio is derived from random samples submitted by each classing office and tested using the Shirley Fineness and Maturity Tester (FMT).
FIN mtex	Fineness (FIN) gives the linear density of the fiber, given in millitex (mg/m).  A fiber with a value of 175 - 200mg/m is average in fineness.  Below 175 is considered fine, and above 200 is coarse.  Fineness values are derived from random samples submitted by each classing office and tested using the Shirley Fineness and Maturity Tester (FMT).
LGRD INDEX	Leaf grade index (LGRD) is a measure of the overall grade of the cotton.  It is a weighted average of the bales in each leaf category.  The weights were adjusted in 1998, so values given after this date will be slightly higher in relation to values from comparable data in past years.  LGRD is measured by Fiber Quality Research using the USDA data.
NO. BALES	Lists the total number of bales classed so far this season.
LEN inch	Length as defined in the LEN 32/in column, only represented in inches.
