variability

"We see changes in the body such as a lowering of blood pressure and heart rate variability so your heart beats slower," says Baroness Kathy Willis, a biodiversity professor at Oxford University.

Roman will have the resolution, sensitivity and infrared wavelength coverage to see these stars and potentially witness their variability as they expel out large quantities of dust near the end of their lives.

They can cope with more variability than previous industrial robots, which had no sensing abilities.

This is mainly due to the variability of the extracts and the fact that each person behaves differently.

While there are clear guidelines as to what you are looking for, Dr Wong says there is still a lot of variability.
