Example: near IR array observations

A raw frame of a young star (DQ Tau) at 3.1 microns, observed with an infrared array.  Can you find the star?

[dqtau lp raw]







Two offset frames subtracted from each other:

[dqtau lp sub]




Column plots of raw and subtracted data:

[dq lp col]

[dq lp colsub]


Surface plots of raw and subtracted data:

[dq lp surf]
