BETA ABSORPTION IT'S A MARKS THE KIND OF SPECTRAL FEATURE DOESN'T IT IT'S A PROCESS ISN'T IT MM BUT IT'S STILL THIS IS A PROCESS FROM NEUTRAL HYDROGEN I GUESS WHAT I'M MEANING IS NEUTRAL HYDROGEN SHOULD BE IN THERE AND THE FACT THAT GUNN PETERSON COMES BETWEEN IT IS JUST A PAIN WELL IT I WOULDN'T HAVE ANY OF IT I THINK I THINK ALL OF THAT IS UM JUST THAT IS PROCESS ISN'T IT MM 'CAUSE THIS DEFINITELY SHOULDN'T BE MARKED BECAUSE THAT IS A PROCESS NOT A A AND IF THAT SHOULDN'T BE MARKED THEN THAT SHOULDN'T BE MARKED OKAY LET'S JUST CROSS EVERYTHING OUT RIGHT BLUE SHIFTED ABSORPTION I THINK IT'S A MODIFIER OF THE THING AND SO IT PROBABLY SHOULD BE THERE OH OKAY MM AS IN WE'RE PUTTING WEAK AND STRONG ABSORPTION WOULD COUNT SO I THINK BLUE SHIFTED SHOULD UM THAT'S TALKING ABOUT THE LINE ISN'T IT SO THAT SHOULD BE IN HMM YES OKAY YOU THINK YEAH THAT'S TALKING ABOUT UH STRENGTH RATHER THAN UM YOU DON'T THINK THAT IT ACTUALLY IS ABUNDANCE REALLY IN A WAY I'M NOT SURE BUT I'M NOT SURE YEAH BUT UM I GUESS IT COULD BE ABUNDANCE B OH YEAH EITHER THAT IF THAT SHOULDN'T BE IN NEITHER SHOULD EITHER OF THOSE YES THAT'S TRUE I THINK YOU PROBABLY SHOULD THEN 'CAUSE WE WILL PUT IN OUR ALIGN STRENGTH UH IF IT'S A F. I OF A TWO LINE STRENGTH WE WOULD DEFINITELY PUT IT IN YEAH THAT'S RIGHT AND I THINK THAT'S WHAT IT'S REFERRING TO EVEN THOUGH IT'S NOT UH I IT'S NOT SAYING TWO THAT YOU ESTIMATE ACTUALLY USING A NUMBER OF LINES IS IT IT ISN'T JUST ONE DISCRETE LINE IN THE SPECTRUM IS IT B A FEATURE WHAT DO YOU MEAN WELL IF YOU T IS IT LINES IN THE SPECTRUM AND YOU'LL UH ESTIMATE ON THE ABUNDANCE ALL OF THE S SPECIES ACTUALLY USE THE OLD LINES UH BUT IT'S A STRENGTH RATHER THAN ABUNDANCE I THINK THAT'S STILL LOOKING AT THE AMOUNT OF FLUX COMING OUT OF THE OUT OF ALL THE F. E. TWO LINES RATHER THAN WE'VE MARKED THING HAVE WE MARKED THINGS LIKE YEAH I DON'T KNOW IF WE'VE MARKED THINGS LIKE SILICONE ONE THROUGHOUT IN GENERAL WE HAVEN'T IF UNLESS IT'S SPECIFICALLY SAYING IT'S A LINE BUT I GUESS THE QUESTION IS JUST AS SPECIFICALLY REFERRED TO A LINE AND I MAYBE IT'S NOT CLEAR ENOUGH TO MARK YEAH LET'S NOT MARK IT THEN WELL LINE NARROW LINE IF IT SAYS IT F. E. TWO LINE STRENGTH THEN WE WOULD MARK IT 'CAUSE YOU'RE TALKING ABOUT THE LINE OF IT RATHER THAN THE EV ELEMENT DO YOU AGREE WITH THAT I THINK SO YEAH THE WORD LINE SHOULD BE IN THERE OR OH WELL WHAT'S NEW LIKE YEAH I THINK THEY MEAN L I THINK THEY MEAN THE LINE STRENGTH RATHER THAN THE F. E. TWO ABUNDANCE I THINK THAT'S WHAT THEY PROBABLY MEAN BUT IT'S JUST NOT VERY CLEAR UH THAT'S A YEAH OH YEAH OKAY UM TAKE OUT LINE MM-HMM AND THAT'S JUST THE WRONG THAT'S JUST THE WRONG COLOUR AS IS THAT I THINK YOU WERE RIGHT THERE YEP YOU'RE RIGHT YEAH AND YOU'RE RIGHT THERE AS WELL THAT'S A PHYSICAL PROCESS OKAY THAT COUNTS YES THAT WAS ONE I WASN'T SURE ABOUT 'CAUSE INFRARED AND IF IT WAS MID INFRAR UH IF IT WAS YOU'D PUT IT IN THAT'S JUST THE WRONG NA THAT'S JUST THIS SHOULD BE A SOURCE NAME I DON'T KNOW W YES I GUESS THE PROBLEM IS DUE TO WHAT DOES THAT M MEAN I PRESUMED IT A E. TWO IS A KIND OF ELLIPTICAL WHAT I DON'T KNOW WHAT THE J. MEANS 'CAUSE THAT'S ONE I JUST DIDN'T KNOW WHAT IT UH I THOUGHT IT WAS A CATALOGUE MM H. ALPHA I THINK SHOULD BE MARKED YEAH
