This plots shows:
- (1) The number of found slitlet spectra
- (2) correcting scale to fit the lenslet model and the SPOS calibration slitlet center point pattern.
- (4,5) The pixel offset between the SPHERE IFS spectra positions of the raw input frame and the lenselet model.
- (6) The pixel offsets in the XY-plane
- (3) The pixel offsets as a function of the optical bench temperature.
The solid lines are empirical non-linear relations.
The dashed line is the empirical relation before the earth quake in 2015-11 and
shows the shift by 0.6 pixel introduced by this event.
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
