After the wavelength calibration is obtained from a MOS arc lamp exposure, the
wavelength corresponding to the center of the CCD is computed (only if all
slitlets are in the center of the CCD). The
values trended here are for the 300V grism with a slit width of
1.0" and the order separation filter GG435.
Data have been acquired using the red-sensitive MIT detector.

Click on any of the plots to see a close-up version.
If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.
The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
statistical averages are indicated by a solid line, and thresholds by broken lines
outliers are marked by a red asterisk. They are defined as data points outside the
threshold lines
"aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
