This plot
This is the trending plot for the ISAAC
spectral response function.
For the setup : LR-J, central wavelength LAM_0 =1.25 mu
These plots describe:
Fig. 1. average efficiency in narrow range [ 1.24: 1.28 ] mu
Fig. 2. average counts in wide range [ 1.15 : 1.45 ] mu
Fig. 3. the spectral slope within [ 1.15 : 1.32 ] mu in 1/Angtroem *)
Fig. 4. average conversion factor in narrow range [ 1.24: 1.28 ]
Details are given on the ISAAC spectral flux page.
QC parameters that could not have been derived are set to zero; they
are currently not (yet) filtered in the plot.
*) Only for the J-band a quadratic function is fit
to the efficiency of which the linear term is trended.
For the other three bands Z,H and K a linear function is fit.
General information
Click on any of the plots to see a close-up version.
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 ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
