Scheduler-oriented night summary of latiss on 2025-10-01ΒΆ
This report is a summary of a night of observing designed to understand scheduler behavior during the night, identify scheduler problems, and otherwise monitor scheduler performance.
All data used for this page comes from "quick look" processing, not the full science processing.

Details on how the above values are computed.
Select a value to plot in the subplot on the right using the dropdown at the top of that subplot.
s_ra,s_dec,altitude,azimuth, andeff_time_medianare values read directly from consdb.seeingFwhmGeomis computed from consdb columns asseeingFwhmGeom = psf_sigma_median * (2 * np.sqrt(2*np.log(2))) * 0.2, where(2 * np.sqrt(2*np.log(2)))is the FWHM of a Gaussian with sigma=1 and 0.2 asec/pixel is a rough pixel scale.skyBrightnessis computed from consdb columns usingskyBrightness = zero_point_median - k*airmass - 2.5*log10(sky_bg_median/(0.2**2)), wherekis a typical extinction for the band (not measured on this night in particular), and 0.2 asec/pixel is a rough pixel scale.nest_healpixis the healpixel ID in nested form, withnside=128. This is useful because similar values usually indicate nearby locations on the sky, and jumps in value usually indicate longer slews. (This is not always true, but it is a better indicator than working from R.A. or Decl. alone. Uncollapse the map below for a key.)

Night visit metric mapsΒΆ
In all of the maps that follow, annotations are similar to those of the "Visit Map" above:
- The orange disk shows the coordinates of the moon.
- The brown disk shows the coordinates of the sun.
- The green line (oval) shows the ecliptic.
- The blue line (oval) shows the plane of the Milky Way.
Maps of numbers of visits and depthΒΆ
Not running on Simonyi, skipping depth section
DDF CadenceΒΆ
No DDF visits
The y-axis (height of the vertical bars) represents the accumulated effective exposure time, teff (as defined above) accumulated over all exposures on the field for the night, colored by filter.
Observation Reason HourglassΒΆ
The hourglass plot below shows the observation reason for each visit over the past month. Each horizontal band represents a timeline for a day. The gray background shows twilight, while the black background is fully night. The moon rises or sets where the dotted line crosses each night's horizontal line, and transits where the thick solid line crosses it.
