Data set would look like this;
1. Lights
2. Darks (no bias subtraction) == lights
3. Flats - low iso
4. Bias, dark flats, however described (low iso) to calibrate flats only - alternatively to keep things equal take so-called bias at same speed as flats, as mentioned previously.
That sounds like a collaborative effort. Thanks guys. I forgot about low iso flats. I think it means double handling, however the flats are created which is unavoidable. Create masters separately and use to calibrate lights.
EDIT. I like the idea of intermediate dark frames.
