Downloading and installing AstroConda with IRAF#

Go to the AstroConda installation page, and follow the instructions to download AstroConda with IRAF. Unfortunately this only works with Python 2.7.

Preparing your data#

ReduceARCES will expect your flats in the red to start with “redflat”, your flats in the blue to start with “blueflat”, your biases to start with “bias”, and your ThAr lamp exposures to start with “ThAr”.

Reducing your data#

First, make sure your iraf27 (or whatever you named it when installing AstroConda with IRAF) environment is activated by doing

source activate iraf27

from a bash terminal.

Copy all of the files in the aesop/iraf directory into the directory where your raw data and cals are. From that directory, do

mkiraf

which will create login.cl in that directory. If prompted to specify a terminal, say xgterm. Edit login.cl to include the following imports

imred
ccdred
echelle
crutil
astutil
images
imgeom
twodspec
apextract
onedspec

Next, open an xgterm by doing xgterm, and do

cl
cl < ReduceARCES.cl

This will extract the spectrum from your data. When prompted to edit the parameters of the tasks that ReduceARCES.cl uses, simply do :q. You’ll have to do this twice at the beginning of the reduction and a few more times in the middle.

Now in order to use aesop, follow the tutorial in Getting started
