I’m calling “phot” within a script, and I’d like to give it three different aperture sizes. If I were
doing this with numbers I would say:

phot(s1,"default","default",datamax=dataxv,datamin=datanv,apertur=“3,5,7",calgori="none",interact-,verify-,verbose-,filter=s2,obstime=s3,annulu=10,dannu=8)

and it would then do photometry through apertures with radii of 3, 5, and 7.

Instead, I’d like to do it using variables. If I do a

phot(s1,"default","default",datamax=dataxv,datamin=datanv,apertur=fwhmv,calgori="none",interact-,verify-,verbose-,filter=s2,obstime=s3,annulu=10,dannu=8)

it works fine. (I declare fwhmv as a real.) However, if I do:

phot(s1,"default","default",datamax=dataxv,datamin=datanv,apertur=fwhmv,fwhmB,fwhmvC,calgori="none",interact-,verify-,verbose-,filter=s2,obstime=s3,annulu=10,dannu=8)

it doesn’t like the syntax. (fwhmB and fwhmC are also declared as reals). So, instead I tried putting them in quotes:

phot(s1,"default","default",datamax=dataxv,datamin=datanv,apertur="fwhmv,fwhmB,fwhmvC",calgori="none",interact-,verify-,verbose-,filter=s2,obstime=s3,annulu=10,dannu=8)

and instead it just does a single aperture with a radius of 3.0.

Thoughts?

Thanks!

The parameter needs to be passed as a string, so you need to first create the string from the script variables. E.g.

string aps

aps = str(fwhmv)//","//str(fwhm//","//str(fwhmC)

phot (......, aperture=aps, ....)

Note you need to also use the concatenation operator '//' to construct a comma-delimited string.
