    • n twilight The light from the sky when the sun is below the horizon at morning and evening. It has generally been agreed by observers in different countries that this light rises in the morn-ing and sets in the evening when the sun is 18° or 19° below the horizon. The former depression is given by Ptolemy, Gemma Frisius, Magini, Kepler, and Gassendi; the value 19° is given by Posidonius and Alhazen. Under some circumstances a second twilight appears, separated by an interval of darkness from the first. Twilight is certainly due to reflection from the upper atmosphere, but the phenomenon is somewhat complicated by the zodiacal light.
    • n twilight Hence, any faint light; partial darkness; shade.
    • n twilight Figuratively, an indistinct medium of perception; also, a state of faint or hazy mental illumination.
    • twilight Bolonging, pertaining, or peculiar to twilight; seen by twilight; crepuscular, as a hat or moth.
    • twilight Faintly illuminated; shady; dim; obscure: either literally or figuratively.

In science:

The procedure of taking twilight flats is automated so we expect the average twilight colors to be rather stable.
Improved Photometric Calibration of the SNLS and the SDSS Supernova Surveys
The fraction of those variations unrelated to changes in the twilight color (but simply to actual changes in the instrument response following roughly a similar pattern) is difficult to estimate.
Improved Photometric Calibration of the SNLS and the SDSS Supernova Surveys
Nevertheless, those variations can be used to set an upper bound on the effect: in all cases a variation of the twilight color by the quoted amount contributes a flat-field error that reaches at most 5 mmag.
Improved Photometric Calibration of the SNLS and the SDSS Supernova Surveys
Variations of the instrument response on shor t time scale: Last, variations of the amplifier gain arise on time-scales shorter than the run and cannot be properly accounted for by the twilight flat-field. A prominent example of an amplifier gain variation is clearly visible on the 2005-10-09 grid displayed in Fig. 5.
Improved Photometric Calibration of the SNLS and the SDSS Supernova Surveys
This feature is present in all bands for this epoch, but since it is not reproduced on other grid epochs we interpret this effect as a variation of the gain between the acquisition of twilight and the observation of the grid.
Improved Photometric Calibration of the SNLS and the SDSS Supernova Surveys
Second, whether the successive twilight flat-fields consistently map the instrument response to uniform illumination.
Improved Photometric Calibration of the SNLS and the SDSS Supernova Surveys
This can be due either to clouds or to a variation of the instrument response that is not corrected by the twilight flat-fielding.
Improved Photometric Calibration of the SNLS and the SDSS Supernova Surveys
Its effect was the scattering at small angles of a growing part of the light, decreasing progressively the flux fraction contained in the core of the PSF (and hence the throughput of the photometry), while leaving the twilight images essentially unchanged.
Improved Photometric Calibration of the SNLS and the SDSS Supernova Surveys
The twilight flat-field is common to all observations in a run.
Improved Photometric Calibration of the SNLS and the SDSS Supernova Surveys
When the sky is pointed into zenith and a set of sky flat field images is obtaine too dark for flat field images, ”observer” takes a few dark fram es and waits until the end of twilight.
