Re: Ecart de continuum

Hi, Usually I use Caltek database to get E(B-V) : https://irsa.ipac.caltech.edu/workspace/TMP_kRqRrd_3787/DUST/HD207260.v0001/extinction.html or https://irsa.ipac.caltech.edu/applications/DUST/ and then click to 'Extinction by Bandpass' For HD207260 they give E(B-V)=0.88 Where is the truth (sic)? Be...

Re: atmosphere independent instrument response

Hi, An other method to get the intrinsic instrumental response and then for each target the corresponding instrumental response taking care about atmospheric absorption is described in the following tutorial: http://spcaudace.free.fr/training/corratmo/ It based on Spcaudace software ( http://spcauda...

Re: Gam Cas proche IR UVEX4 G600 slit 15µ res 4860

Hello,

Pour être sûr de la détection de la binarité une résolution serait plus importante.
Vu que R croît avec Lambda, cela ne devrait pas être difficile.
Pour faire de la physique stellaire, il faut au moins R>=10 000.

Re: SN 2022hrs bright in NGC4647

Hello,

Bertrand tu sembles confondre décalage Doppler et vitesse d'expension, respectivement ici de 248 A (-11699 kms) et 0.5fwhm=~100 A (4830 kms)

Re: Présentation

Bonjour et bienvenue Norbert, En 2019 j'avais fait quelques études de binaires spectro avec résolution d'une partie des paramètres du système. Tu peux trouver un tutoriel " Les binaires spectroscopiques, c'est fantastique ! " que j'ai rédigé à cette occasion ici : http://wsdiscovery.free.f...

Re: Geometrics slant and tilt correction with Spcaudace

Hi Stan, Hi Benjamin, In this way I know the light spectrum and calibration spectrum are both identically corrected for tilt. How can I do this with Aud'ACE? See the provious post, I answered to that question. With pipelines all theses tasks are done for you. Tilt and slant parameters are stored in ...
