Imaging FTS: A Different Approach to Integral Field Spectroscopy
Figure 4
(a) Example of the sky subtraction for the spectrum of a bright pixel (1 h 36 m 54.1 s; +15° 46 m 10.8 s). (b) Example of a Gaussian fit on the spectrum of a bright pixel. (c) Close-up on the contours map of NGC 628 selected by HIIphot; the field of view is . The red cross identifies the position of the bright pixel used for the previous sky subtraction and Gaussian fit examples. The green cross identifies the pixel with H in emission at 2 limit of detection. (d) Example of the spectrum of a 1.1 arcsec2 pixel with H in emission at 2 limit of detection.
