The noise-pdf-browser web service returns browsable views of PDF noise plots.
There are three service query methods:
Produces a grid of PDF images where the columns are selected calendar intervals (for example months) while the rows are selected targets.
For specified target, produces a plot of a calendar interval (for example a year) along with plots of the sub-intervals (for example months) that comprise it.
Produces a column of spectrogram images for selected targets and time range.
Produces a list of targets with the date-ranges of available PDF information.
