... The choice of exposure time generally depends on the signal-to-noise ratio required to meet the science goals. ... See "Overhead Times" on page 29 for more information about exposure timings.) ... For example, shortening an exposure from 400s to 350s has no effect on orbit packing; they both require 9 minutes to execute ( CLOCKS=NO, the default setting). On the other hand, shortening an exposure from 180s to 160s trims the execution time by 2 minutes (again CLOCKS=NO, the default setting). ...

Detector on-chip integration (DIT): seconds. to your chosen value - a separate page gives recommended values to use for DIT - for modes 1 and 2 below you may wish to start with the maximum recommended values as these will minimize the effect of read noise (a total object exposure of Y secs with DIT=X secs will produce Y/X lots of read noise) and give you a lower limit on the time needed. ...

... Flats : Properly exposed flats over all echelle orders require a two-step process. Flats are taken both with and without a CuSO4 (aka "blue") filter in the beam. ... Suggested exposures are 7 seconds ("red"; no filter) and 240 seconds ("blue", CuSO4 filter) yielding S/N values of ~480. The filter for "blue" flats is listed as "blue" in the Config window in Echelle control under Remark. ... Exposure times for objects can be derived from the following plot: . ...

To get any time that is not printed here, you can add, subtract, multiply and divided at will to get the desired time. i.e.) 2.5 min=2 min+30 sec= 456+114=570 so you would type in 570 for a 2.5 min exposure. You must be out of windows for these times to work. Scott J. Wolk . Mon Nov 25 15:41:03 EST 1996

... It is not always easy to identify ``the'' time of an observation. Some instruments record the time at which the observation began; some record the end of the measurement, or even the time at which the readout was recorded; very few record the middle of the exposure. The ESO Archive records the starting time of the observation, recorded in a FITS-header keyword named MJD-OBS . ... In any case we would need this information for weighting purposes. ...
