Question regarding slit_y_low and slit_y_high in stage 2 with data from NIRSpec G395H of WASP-39 #690

Instrument

NIRISS (Stages 1-3)

What happened?

I understand that my ecf files should be like the demo ecf files of the version I'm using, I'm currently using v0.10 and in the demo file of stage 2 slit_y_low and slit_y_high are set like this:

slit_y_low -1 # Use None to rely on the default parameters slit_y_high 50 # Use None to rely on the default parameters

But my y axis in the fits files I'm using from MAST goes from y = 0 to y = 32, and using DS9 I saw that the spectral trace falls between y = 6 and y = 27, my guess would be to set slit_y_low to 6 and slit_y_high to 27, but since I've been recommended to follow the demo files, I'm unsure on what to set those two values.

Error traceback output

none.

What operating system are you using?

Ubuntu 18.04.6 LTS

What version of Python are you running?

Python 3.9.7

What Python packages do you have installed?

I don' t think it's needed.

Follow the demo file. Do not adjust these two parameters.

Ok, thank you :)
