SKSS_FocusingCorrelationCompleted

Description

Event sent when the focuser correlation has been completed.


The JSON object returned in the data field of the JSON response contains the information displayed in the information tab of the focusing loop of the advanced GUI.


Detailed description of the properties of the JSON object

Time

Local timestamp of the event

TimeUTC

UTC timestamp of the event

FocusingIterationCount

The iteration of the focusing loop

FocusingIterationFrameRate

The time in milliseconds for processing the frame

FocusingIterationAverageFrameRate

The average time in milliseconds for processing frames

CorrelationFactor

The correlation factor in percent

CorrelationThreshold

The correlation threshold. If the correlation factor is below the threshold focusing is suspended

PoorCorrelation

True when the correlation factor is below the threshold. Otherwise, false

SNR

Signal to noise ratio of the frame

DSL

Dynamic signal level of the frame

FocuserPosition

Position of the focuser is steps

FocuserCFZPredicateUpperBound

Upper bound predicate for the critical focus zone in steps

FocuserCFZPredicateBestFocus

Best focus predicate in steps

FocuserCFZPredicateLowerBound

Lower bound predicate for the critical focus zone in steps

FocusingMinCFZ

Lower bound of the critical focus zone in relative roundness (0 = is the best focus)

FocusingMaxCFZ

Upper bound of the critical focus zone in relative roundness (0 = is the best focus)

FocusingFilter

Current filter of the filter wheel. If no filter wheel “No filter” is returned

FocusingReferenceRRDN

Reference relative roundness currently used by the focuser. This value can be different for each filter of the filter wheel

FocusingCorrection

Corrections in number of steps sent to the focuser

FocusingKc

System gain in micron per percent

FocusingKs

System gain in percent per micron

FocusingPoleValue

Pole value between 0 and 1

FocusingMeanX

Root mean square on X axis

FocusingMeanY

Root mean square on Y axis

FocusingStdevX

Standard deviation on X axis

FocusingStdevY

Standard deviation on Y axis

FocusingMajorStdev

Major axis standard deviation

FocusingMinorStdev

Minor axis standard deviation

FocusingNoCorrection

True if no correction is sent to the focuser. Otherwise false.

FocusingARDN

Absolute roundness in percent

FocusingAverageARDN

Average absolute roundness in percent

FocusingMinRRDN

Lower bound of the relative roundness of the focusing envelope in percent

FocusingMaxRRDN

Upper bound of the relative roundess of the focusing envelope in percent

FocusingRRDN

Relative roundness in percent

FocusingAverageRRDN

Average relative roundness in percent

FocusingAlpha

Current focusing correlation ellipse angle

FocusingAlphaCal

Calibrated focusing correlation ellipse angle
