This plot
This plot visualizes the delivery times for the autoDaily processing. Delivery time
is defined as the time elapsed between the acquisition of the last input raw file in an AB (as recorded in the DATE timestamp in the header) and the
finishing of the processing job. The plots distinguish between ABs triggering
HC plot updates and other ABs (#1), and between day and nighttime calibrations
(#3 and #4). The delivery times are dominated by:
- the cronjob pattern of autoDaily (once per hour),
- the average delay by the DTS,
- the template effect (processing of an AB is possible only after the last input raw
frame has been taken and is available from the archive),
- the last-template effect (the current last template is processed only if it is older than one
hour, in order to avoid broken templates processing),
- the AB processing time itself,
- possible other effects (the most important one being dependencies).
There are also the 'delay times' stored in the database table, which are
defined as time elapsed between the archiving of the first input raw file in
an AB (as recorded in the ARCFILE name) and the finishing of the processing
job.
The purpose of this plot is to monitor these figure of merit and control the
quality of the autoDaily processing scheme.
The distinction between day and night calibrations is based on the ARCFILE
timestamp: anything between T22 and T09 is called nighttime. Calibration-wise,
this
time window is normally spent with standard stars and twilight flats only. In
exceptional cases daytime calibrations might start before T10, then being
counted as nighttime. Disregarding such pollution effects, one can expect that
the nighttime calibrations have their own processing pattern which differs
strongly from the daytime pattern. Most prominent effect is that they often depend
on follow-up daytime calibrations. This is why their delay may sum up to many
hours. Therefore they are marked and plotted separately from the daytime
calibrations (plot #3).
The plot #1 distinguishes (daytime) calibrations with and without HC update.
The QC1
database table permits filtering by raw_types and other parameters.

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 ↓)
