Christian, Thank you for the link to some very interesting presentations, not only on spectroscopy, and congratulations to all the presenters. Bernard ... ...

Until now I have avoided the need to splice/join two or more spectra but recently, to monitor nova development over a 3000A range, I am faced with that task....
Greetings Bernard, I use Vspec to join spectra. After wavelength calibration one can merge spectra using the "join" function. Best, Jose ... From: Bernard...
Hi all :) Some of my students need a Betelgeuse and Rigel spectrum. basically to get surface temperature And some basics components. (not need a High...

Hi Jean-Baptiste, I have film spectra of Betelgeuse and Rigel, resolution from 1300 to 2700. They show some basic components, but are not corrected to show...
Hi :) 2008/12/8 Tom Buchanan <tombuchan@...> ... I you could do this, yes. I should need another for spectrophotometrics, but ours could help them in...
Jean-Baptiste, I did that "TP" with my students in class of "Seconde" May be that link might help you. http://e.sarrazin.free.fr/astro-alpes/entree.htm and...
Just a few more words. That "TP" was done using Vspec in order to calibrate spectras as well as to determine the photosphere's temperature (betelgeuse and...
Hello ! That's my first post ! I am waiting for the scope to cool off a bit more and Orion to get higher in the sky . If everything goes as planned I can send...
Thanks Ken and Jose. I have just tried using Vspec (the latest version) to JOIN two overlapping spectra from a southern nova I am following. When I try to do...
I have uploaded the two spc files I am having problems joining into the folder "Join files' in the Files folder. Any help with working out how to join/splice...
Bernard, Just tried to open your files, but my V3.5.1 VSpec won't recognise them as .spc??? Can you double check and reconfirm they are OK?? If you're...
Ken, Hmmm ... I created the spc files using the latest Vspec (3.6.1). I will have to wait until I'm back in Melbourne (tomorrow) to check if I'm able to read...
Hi If you download from the Yahoo group, files will be saved with .p7b extension - if you make sure you save them forcing the .spc extension they will open...
Valerie, Thank you for the spc/p7b extension explanation, and I look forward to a solution to the 'join' problem. Bernard ... From: valerie.desnoux To:...

Benji, Thank you for your help. I am away from home until tomorrow, so cannot check/test what you have done. I will look into the FIT format problem. Yes, I...
Hi JB, I am sorry that I can not send you the spectra. My scanner quit working. Tom Buchanan ... From: Jean-Baptiste BUTET To: spectro-l@yahoogroups.com Sent:...
One of the main problems I have found with making overlapping spectrum 'windows' is that every time the grating angle is changed a new flat field is required....
Hi Bernard, Unless you are particularly interested in the continuum, I would suggest forgetting the "standard star" and just normalising your spectra using a...
Hi all, The discussion I had recently on the German VdS spectroscopy group with two of the professionals there might be of interest here too (attached) It...
Hi I found the issue on the vspec code. It is regression due to the new function "normalisation to 1" which does create anymore a serie. Until I pusblish a new...
oops, I forgot to mention one step, before you move the intensity series into the norm series, make sure you normalized them. (click on the normalized button...
That's magic!! I don't understand the procedure, but really works!! In attachment the joined spectrum of Bernard. Cheers, Jose ... From: valerie.desnoux To:...
Jose, Valerie, Yes, that is 'magic' .... now I will have to see if I can reproduce it, and also join the 'blue' end spectrum to the mid and red. Thanks, ...
Robin, Your long VdS exchange makes for very interesting reading, but in the end I have no clearer idea as to the 'correct' method to be used for spectrum...
