Interactive 2Mass All Sky Survey Data Chart
The image generated uses the PHP gdlib library to overlay plotted points on top of
an image "template" http://twelveparsecs.com/2mass/blank-graph.png
The data from the 2Mass All Sky Survey was imported into MySQL from the xsc_aaa and xsc_baa files, located at:
ftp://ftp.ipac.caltech.edu/pub/2mass/allsky/
A selectable filter is shown below to display items under the selected magnitude in the K band.
A rough color filter has been applied for reference purposes.
h-k < 0 is Blue, h-k > 0.5 is Red, and anything else is white.
To view the plot points based on the selected magnitude,
Select an option and click the [Submit] button.
