ODT and NGC 2008 - NGC performance - Daily projects

Q: NGC性能的关键演示与达标点是什么？

文档提到RON < 3 e- @ 50 kpix/s 的演示，并强调MUSE等多套需求得到满足，同时NGC相比FIERA在拾取噪声方面更具免疫性。

Q: 软件与数据/接口相关的性能指标有哪些？

文档给出软件启动时间 < 2.5 s，并说明标准ADC以1 MHz运行，且有3 MHz与40 MHz高性能开发版本。

Q: NGC-AO的计划与当前状态包含哪些内容？

计划包括开发通用WFS模块、测试OCam控制器、组合NGC数字与OCam模拟电子，并在LLCU层面建立sFPDP接口；状态记录了偏置与时钟驱动板到货、固件原型验证，以及在11月实现“laboratory light”。
