  • Why to use 3D Spectroscopy ?


Euro3d rtn kick off meeting iac tenerife july 2 4 2002

  • Why to use PMAS (in Nod & Shuffle mode)?

  • Because the interlaced observations of target and sky is the only way to obtain a reliable sky subtraction in the near-IR (impossible with long-slit spectroscopy).

HST (NICMOS) photometry of NGC 221 (Ravindranath et al. 2001)

> 6 mag

  • single spectra

  • coadded spectra (  10–30 spectra )

  • sum over the whole IFU ( 256 spectra )

  • Example: NGC 221

  • First reliable CaT - gradient in an elliptical galaxy: flat !

  • but : NGC221 exhibits a gradient in Mg2 !

  • E galaxies arenot composed of simplestellar populations  complex star formation history

Conclusions

  • interlaced NODS 3D spectroscopy works

  • random noise sky subtraction, no systematic residuals

  • no MIRACLES : NODS does not beat the shot noise !

  • significant overhead penality

  • at CAHA 3.5m, specifically: not applicable to point sources

  • opens opportunities for going faint in bright/grey time

  • think of ELTs : using less than ideal obs condx. !
