Fill in zero or more fields with desired criteria and hit 'Search'. Leave the field empty and hit 'Search' to get all observations. Fill in several fields and the result will be observations matching all those criteria. Longer manual at the bottom of the page.

There are two types of search forms available to interface with, the simple form and the advanced form.
The simple form can be used if you don't want to bother about details too much and just need one of the most needed
functions. For all fields the general rule is, if you don't fill it in, it does not restrict that quantity or value. The different input fields for the simple form are:
Date begin - this only returns results after or on this date. Format has to be in YYYY-MM-DD.
Date end - this only returns results before or on this date. Same format as date begin.
Duration interval - this gives a minimum and/or maximum duration for the sequence. Format is HH-MM.
Target name - this searches for obeservations with at least this in the targetname. Format can be anything
μ interval - this gives a minimum and/or maximum value for μ. Format is a (decimal) number
There are some other options which can be used to tweak the way results are returned, but this is rather straightforward. If not, try it out.
The advanced form has the options noted above, and the following extra:
Time begin - this gives results which begin after or at a certain time of the day, e.g. 11:00. Format HH:MM
Time end - this gives results which end before or at a certain time of the day, e.g. 13:00. Format HH:MM
r0avg interval - this gives a restriction on the value of the Fried parameter to return. Format is a (decimal) number
Cadence interval - this gives a range for the average cadence (time between frames) to return. If you want high temporal resolution, choose a low cadence. Format is a (decimal) number
Amount of gaps - this gives a means to search for a certain quality of observations. A gap is defined as a time difference between two frames which differs more than two seconds from the mean cadence. Format is an interger
Image count - gives a minimum and maximum amount of images per obervation to return. Format is an integer
Filters used - gives the possibility to include or exclude certain filters.
Wavelength interval - restricts the wavelengths observed in certain observations. Format is a (decimal) number
The results are displayed below the search form and can be presented in a 'Single-wavelength' mode or in an 'Observations' mode. The first gives a unique combination of the used filter and time observed while the latter only seperates observations done at different times, the different filters are grouped together.
If this explanation is unclear, just try it out.
An overview of the data returned is (for single wavelength results):
Date observed in YYYY-MM-DD
Time interval observed in HH:MM:SS-HH:MM:SS
The duration of the observation (which can also be deduced from the previous column)
The average value for r0 (see above for explanation)
The target observed, usually an AR number or something else
The value of μ of the observation
The filter used for this specfic observation
The wavelength at which is was observed
The number of positions in the spectral line at which images were taken
A sample image
Details of the observation, including the average, maximum and minimum values for r0, the amount of images,
the cadence with the quality of the dataset (good is less than 3 gaps, gapped is less than 6 gaps, bad is more than 5). There are also several links pointing to the Mees AR Map, the detailed page, a plot of r0 vs time, the data itself and a search query in the 'Observations' mode
In the observations mode, most things are the same, except there is also some info on how many movies (mpgs) and cubes (datacubes made of fits files) there are. Additionally, this mode shows when an observation only consists of a mosaic.
