Recommended spectral resolution
Posted: Sat Jul 21, 2012 10:49 am
Here the spectral profile in function of resolution power (Lambda / Delta_Lambda) for AZ Cas:
For observe fine Halpha line evolution, resolution of R=10000 or upper is prefered
(the LISA spectra at R=1100 - 23 microns is for global near infrared survey -
High spectra resolution mandatory - I have used a special LISA with an infrared blazed grating ).
(but maybe worth to try Lhires with 1200l/mm grating – 23 microns slit...)
