From URL
If you do not specify the file type, then VOStat will try to
guess it from the extension of the file name at the end of the URL.
- .dat or .txt: space/tab
separated ASCII format.
- .csv: comma separated ASCII format.
- .fits: FITS format (just table, no image).
- .vot: VO table format
If you are using a URL that does not have such an extension
(
e.g., a query URL) then you will need to choose the file
type explicitly.
For ASCII tables, please ensure that the first line of text
contains the variable names. Variable names must not have
embedded space in them, unless the names are enclosed in
quotes.
A good dataset to practice VOStat functionality is
a
table of 20 properties of 113 globular clusters in the Milky Way
Galaxy. Click here
to work this data set.
From local file
If you do not specify the file type, then VOStat will try to
guess it from the extension of your file.
- .dat or .txt: space/tab
separated ASCII format.
- .csv: comma separated ASCII format. (If you have data in MSExcel format, please save it
as a csv file before loading it into VOStat.)
- .fits: FITS format (just table, no image).
- .vot: VO table format
For ASCII tables, please ensure that the first line of text
contains the variable names. Variable names must not have
embedded space in them, unless the names are enclosed in quotes.
From SAMP
Current SAMP status:
SAMP communication requires a signed java applet. When you use
this feature for the first time your browser may pop up a window
asking for your permission. You have to allow the applet to run
to establish SAMP communication.
- A red dot means VOStat is not connected to SAMP. Clicking on
the dot will coonect VOStat to a hub (if one is found running).
- A static green dot means VOStat is ready to receive data.
- A throbbing green dot means the data set is being uploaded.
- A throbbing R icon means the data set has been already
uploaded to the server, and now is being read into R. This may
take some time.
In order to load data into VOStat by SAMP you must have some
SAMP-aware VO tool (like Topcat) running in your machine.
Any data set broadcast from your local VO tool
automatically goes inside VOStat.
