Refer to the current Denver sectional excerpt. Colorado Air and Space Port (CFO) is charted with "CT - 120.2" and "ATIS 119.025" above its "5515 *L 80" elevation/runway line. What does "*L" mean here, according to the chart's own legend?

Why: The chart's "Additional Airport Information" legend distinguishes two lighting codes: a plain "L" means "Lighting in operation Sunset to Sunrise," while "*L" means "Lighting limitations exist; refer to Supplement." Colorado Air and Space Port's "*L" tells a pilot its runway lighting has some restriction and the Chart Supplement should be checked for the details, rather than assuming full dusk-to-dawn lighting is available.

• Invents a permanent-closure meaning for "*L" — the chart's legend describes it as a lighting limitation to look up, not a closure.
• Invents an on-request condition; the legend's actual text for "*L" directs a pilot to the Chart Supplement for the specific limitation, not to a request-based lighting procedure.
