I want download "data of Star brightnes"

Recommended Posts

As John has said, there are other, simpler sources of star magnitude data. If you really need to download the Kepler data, you're a braver man than me!

You may find more information at  http://exoplanetarchive.ipac.caltech.edu/docs/documentation.html#general

As I understand it, the information is primarily designed to be viewed on-line at http://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=missionstars

The column related to magnitude which I think you are looking for is V-band [mag] If you can find a way to download all this the internal column name will be st_vmag†

If, and a big if, the information you need is contained at http://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=missionstars

You should be able to select the columns you want and click on "download" in the menu bar above. This will give you several download options in formats which you may be able to use.

I want values of "brightness of a star" for a month or more, not one time only.

You're a braver man than me, but looking at the data column definitions you want the data from the column 'st_vmag†' for your given range. Unless of course I'm wrong..... It could also be 'st_mbol' if you want bolometric magnitude or any of the 'st_wise#' columns if you want the 2MASS or WISE photometry data. I'm certain there are also other routes.

I'm rambling, Ignore me, I'm basically asleep, and Patrick already said this.
