Resolution chart is updated

Enhanced digital-camera-resolution chart, designated the QA-77, is based on the original ISO-12233 specifications but has been improved with extended resolution ranges and more usable features. The QA-77 chart has a resolution range from 100 to 4000 line widths per picture height (lw/ph) on the central hyperbolic wedges and up to 2000 lw/ph on the corner wedges. This is twice the resolution performance specified in the ISO-12233 standard. The QA-77 target is available on high-quality reflective material in three
overall sizes: 200 × 356, 100 × 178, and 400 × 711 mm.
