GDC Curtain Spacing Lookup

Audit actual GDC center spacing against independently measured asymmetric curtain thicknesses, retaining negative overlap; not symmetric Lyre lean projection or universal canopy architecture.

Description

Divided-canopy clearance depends on each curtain’s measured width.

Divided-canopy clearance depends on each curtain’s measured width. A signed gap preserves overlaps for review.^[1]

Enter nonempty aligned nonnegative dimensions and nonnegative minimum gap. Return signed gaps and zero-based stations strictly below the minimum.

When to use GDC Curtain Spacing Lookup

Use GDC Curtain Spacing Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. No canopy architecture recommendation, growth response or load design is provided.

Prepare the measured vineyard records, aligned lists and independently verified local limits or catalog requested. Keep units, crop stages and observation periods consistent.

How to use GDC Curtain Spacing Lookup and understand its results

Prepare the measured vineyard records, aligned lists and independently verified local limits or catalog requested. Keep units, crop stages and observation periods consistent.
Enter observedGdcCurtainCenterSeparationsM, observedLeftCurtainHalfWidthsM, observedRightCurtainHalfWidthsM, callerMinimumClearCurtainGapM using the field table and calculation rules, then run the tool.
Read observedGdcClearCurtainGapsM, stationsBelowCallerClearCurtainGap. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
observedGdcCurtainCenterSeparationsM	Observed gdc curtain center separations m	list of number	Required
observedLeftCurtainHalfWidthsM	Observed left curtain half widths m	list of number	Required
observedRightCurtainHalfWidthsM	Observed right curtain half widths m	list of number	Required
callerMinimumClearCurtainGapM	Caller minimum clear curtain gap m	number	Required

Enter nonempty aligned nonnegative dimensions and nonnegative minimum gap. Return signed gaps and zero-based stations strictly below the minimum.

gap=centerSeparation−leftHalfWidth−rightHalfWidth

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
observedGdcClearCurtainGapsM	Observed gdc clear curtain gaps m	list of number
stationsBelowCallerClearCurtainGap	Stations below caller clear curtain gap	list of number

Limitations and assumptions

No canopy architecture recommendation, growth response or load design is provided.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Leaf Pulling Cluster Zone Percent Calculator: Leaf removal shares differ when normalized to the cluster zone or entire canopy. Keeping both denominators visible supports consistent comparison. For a complementary task, use Catch Wire Levels Spacing Calculator: Catch-wire vertical spacing is measured between ordered levels. A chosen gap band can identify deviations from a local plan.
