Lockheed Martin Ships NIR Camera for James Webb Space Telescope

"Lockheed Martin [NYSE: LMT], under a contract from the University of Arizona, has completed assembly and testing of the Near Infrared Camera (NIRCam) and has shipped the instrument to the NASA Goddard Space Flight Center in Greenbelt, Md. NIRCam is the prime near-infrared imaging instrument for NASA’s James Webb Space Telescope (JWST)".

Calibrating and validating with VISION (a quick view)

This is a quick exercise about how to use VISION to develop a Regression and to validate it with an independent test file.

I used in this case the Shootout files from 2002, where we have the same samples for calibration scanned in two instruments (same type), this files are CALIBRA1 (scanned in Instrument 1) and CALIBRA2 (scanned in instrument 2).

We have  another sample set for testing the calibration, TEST1 (test samples scanned in Instrument 1) and TEST2 (test samples scanned in Instrument 2). The idea of the Shootout exercise was to develop a calibration in Instrument 1 and transfer this calibration to Instrument 2, the best way possible.

In this exercise I just develop a PLS calibration with the CALIBRA1 and test it with TEST 1, but how this calibration performs with TEST2, we will see it in other post.
