... For example, MIL-PRF-55310D defines frequency-temperature stability as follows: 6.4.16 Frequency-temperature stability. The maximum permissible deviation of the oscillator frequency, with no reference implied, due to operation over the specified temperature range at nominal supply and load conditions, other conditions constant.

... 76 AN ASSESSMENT OF PRECISION TIME AND TIME INTERVAL SCIENCE AND TECHNOLOGY The short-term stability of an oscillator is measured by its Allan deviation, denoted by oy(~, which is the square root of one half the average of the squares of the differences between successive average normalized frequency departure, averaged over the sampling time a, under the assumption that there is no dead time between the averaged normalized frequency departure samples.
