Tycho Epoch Photometry
Tycho epoch photometry, as released in 1997, is available for 13843, mainly variable, stars. The displays show the epoch photometry in BT and VT. The epoch and orbit for an observation are shown in the boxes at the lower right, as the cursor is put on the data point.
For periodic variables, the folded light curves in BT, VT and BT-VT are also shown.
