Warning! Most of the template spectra currently do not cover the full wavelength range of X-SHOOTER!
NEXP or NINT
Note! The current version of the ETC includes the 0.6" and 0.9" NIR slits without the K band blocking filter. For the preliminary performances of the new 0.6" and 0.9" slits with the K band blocking filter please refer to the X-shooter User Manual.
In UVB and VIS, the total exposure time is the product of DIT (Detector Integration Time) and NEXP (Number of EXPosures): T = Texp × NEXP.
In NIR, the total exposure time is the product of DIT (Detector Integration Time), NDIT (Number of DITs) and NINT (Number of INTegrations): T = DIT × NDIT × NINT.
