How to use the Hipparcos/Tycho WWW Interface
In order to to submit your request press the "
button. If you want to reset all the fields back to the way they where
before you started entering qualifiers in them, press the
reset" button. (You could try to edit the "Dateobs"
field above and then press the "Reset" button).
|Setting up output modes|
It is worth remembering that the checkboxes that appeared to the left of the
query items on the query form are what determine which columns appear in the
tabular output. If, for example, you have made a query and you can't find
the telescope name on the output table, then go back to the query form and
press the telescope checkbox and resubmit the query.
How to limit the number of retrieved records?
Right now, there is a default limit of 1000 in number of records one can
retrieve from the database. If you are reaching this limit in your query
result, it is more than likely that there are other observations that
match your query criteria. You can either modify this limit or respecify
your query. For internal reasons there is a hardcoded limit setup to 1500
Want more info on each retrieved records?
For each records retrieved from the archive, there is a more link written
as M. This allows the user to retrieve all known information
concerning this particular entry.
You want to use a full screen mode output?.
There is a selection box on each form wich allows the user to be able to
retrieve the information from each archive in full screen mode instead of
the default tabular format. This is quite useful when only few records are
expected since this mode could generates a tremendous amount of information.
|What about the target name|
The second mode is using the Hipparocs/Tycho star number. This only works if you just happen to know exactly which object you're looking for.
