This is the trending plot for the ISAAC photometric zeropoints for the SW-arm
These plots describe:
1. Photometric Zeropoint SW arm, J filter (lam = 1.25 mu), not corrected for atmospheric extinction.
2. Photometric Zeropoint SW arm, H filter (lam = 1.65 mu), not corrected for atmospheric extinction.
3. Photometric Zeropoint SW arm, Js filter (lam = 1.24 mu), not corrected for atmospheric extinction.
4. Photometric Zeropoint SW arm, Ks filter (lam = 2.16 mu), not corrected for atmospheric extinction.
The raw frames have been flatfielded. No illumination correction and
No linearity correction is not applied.

General information
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 ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
