So if you have understood the steps, but need to add annotations over an image, repeating those steps individually will be annoying. Therefore in this section, we will summarize all the steps in a single script that you can simply copy-paste into a text editor, configure, and run. Necessary files: To run this script, you will need an image to crop your object from (here assuming it is called ah_f160w.fits with a certain zero point) and two my-figure.tex and report.tex files that were fully included in Annotations for figure in paper . Also, we have brought the redshift as a parameter here. But if the center of your image always points to your main object, you can also include the Query command to automatically find the object's redshift from NED. Alternatively, your image may already be cropped, in this case, you can remove the cropping step and # Parameters. sblow=22 # Minimum surface brightness. sbhigh=30 # Maximum surface brightness. bdir=build # Build directory location on filesystem. numticks=7 # Number of major ticks in each axis. redshift=0.619 # Redshift of object of interest. zeropoint=25.94 # Zero point of input image. scalelineinkpc=20 # Length of scale-line (in kilo parsecs). input=ah_f160w.fits # Name of input (to crop). # Stop the script in case of a crash. set -e # Build directory if !
