This plot displays PWV values for Paranal, from radiometer (LHATPRO) data, and from UVES and X-SHOOTER standard stars. Since April 2015 the LHATPRO data are available in the ambient database, retrieved from there and displayed here.
Until
2013-12-12, there were also data
from CRIRES emission line fits.
It displays a closeup of the last 10
days. This format is intended to assist with operational planning based on the
PWV situation. Plot #2 is a closeup of plot #1, emphasizing data values below
5 mm.
Find more information about the underlying data in the "This plot" section of
the main plot ("PWV").
General information
Click on any of the plots to see a close-up version.
The latest date is indicated on top of the plot.
If configured,
- data points belonging to the latest date are specially marked
- 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
