Basic program:
10:00 start, discussing Isis and working on processing people's spectra. Looking at stacking darks, bias, calibration flies.....why these are needed for different spectroscopes.
11:30 Morning Tea
12:00 Bass project . How program works, what it's useful for.
BAA data site for spectra.
Lunch.....please bring something.
( Kerry is bring two quiches, I have an Indian snack box, plus biscuits for morning tea. Can someone bring rolls or bread stick and other nibbles. There should be around 6/7 of us.)

Andy will be joining us Friday evening so we will have a chance to chat to him then as well as on Saturday.

Excellent day today! Many thanks for arranging this Kate, and to Andy Wilson for clearing up a lot of mystique in getting ISIS to work. Really impressed myself that my final processed image of Vega exactly matched the Pickles reference image! There is also a really useful thread on the BAA Spectroscopy Forum : https://britastro.org/node/8156
with a step by step guide by Anthony Rodda.

Andy has agreed to come back in the new year and work through BASS project with us and anyone one else we wish to invite.

Maybe I'll be up to speed with rSpec by then.

We can do some practise on Friday evenings if it will help

Some reading on various forums, etc, suggests that, on balance, flats for slitless spectroscopy (ie, Star Analyser) are not needed. That's a relief, I'm sure.

I didn't actually use flats darks or bias with the star analyser when it was a bright star. I did use darks for dimmer stars or nebulae.

This is probably the most meaningful spectra I have ever taken! Here's a spectum of Vega calibrated for, darks, bias, and smile,taken with an Alpy and compared to library reference standard.All processed in ISIS and GNUPLOT.[[File:Vega_spectrum_20161022_dgs2.jpg|none|auto]]
