View a big list of images with ds9. Mark selected images and create
two lists of images: one for marked images, and one for unmarked images.
If the input list (list.name) has a corresponding Text file (list.name.Text)
then the conetnets of eac Text line will be drawn into the image using a color and fontsize
specufied interactively by the user at run time.
% ds9_list_load list.1
% ds9_list_load --help
ds9_list_load:
Display a set of images listed in a file. Mark selected images with a circle marker.
I have added a useful feature that allows us to overplot text information for the
image displayed by ds9_list_load. The text lines are read automatically from a file
whose name is linked to the basic input file. If the input file is named list.BIAS,"
then the file of text lines is named "list.BIAS_Text". Below I show a full demo
run and the resultant image.
% cat list.BIAS

Boot Head Jones # I can use any line of text
% ds9_list_load list.BIAS
# I interactively specify the font color and size, text X,Y placement, and x,y size of ds9 window
# I used font color=yellow, fontsize = 20, X,Y=400,400 window x,y = 900,900
At the end of this run, I would find two new files:
ds9_list_load.mark == images with a circle region marked
ds9_list_load.nomark == images with no circle region marked
I usually use ds9_list_load to generate the files ds9_list_load.mark and ds9_list_load.nomark.
Using these lists it is easy to write scripts that clean images lists or operate only on selected
images.
