Survey is an on-line service which allows users to pick a region of the sky and obtain images at a number of wavelengths.

To read the on-line documentation click here ; links to publications can be found here; Villa-Elisa-TP-plots now are here.


To access Survey enter RA and DEC or gal. longitude and latitude in the Coordinates box and enter the map size and tabular interval (optional). Choose a coordinate system, projection type, and a survey.

Enter Coordinates :
(e.g. 18 15 00 -12 00 00 for RA-DEC or 18.5 +2.5 for L-B)
(A "+" or "-" is required in front of DEC/Latitude in order to distinguish between the RA and DEC in the coordinates field.
In the case of RA/DEC do not use any dot along with the digits.)

Select Map Size in degrees (in x and y):

Select Tabular Interval in arcmin in x and y (default = -1.0 ==> original values) :

Choose Coordinate system :

Choose Projection type :
