There is a single form for extracting observations of minor planets, comets and natural satellites. As long as you follow the guidelines below when entering designations, the script will figure out what type of object you are trying to extract. You may mix the three classes of designations in a single request. You may optionally restrict extraction to observations made between certain dates or by certain observatory codes. Some guidelines on how to enter requests are available.
You are advised that some requests may return many thousands of observations. Other requests, because of the date/observatory code criteria chosen, may return no observations.
Also, certain program codes will cause screen output to appear truncated. A view of the source code for the returned page will show the full observations. To avoid this problem, it is recommended that you use the "save to local disk" option, rather than the "display to screen".
The general form for entering requests is as shown below:
<designation>[;<date>[-[<date>]][;<oc>[,<oc>...]]where <date> is a YYYYMMDD-format date, <oc> is a three-character observatory code and optional elements are shown enclosed by [...]. If multiple observatory codes are requested, separate the codes by commas. Placing a tilde character (~) as the first character of the observatory code list will suppress output of observations from the listed sites.
The valid forms for entering designations are shown below:
