VIMOS_IMA_DET_NOISE(7)

💖 VIMOS_IMA_DET_NOISE 💖

okay bestie, you found it — this is the section 7 page for vimos_ima_det_noise, straight out of the vimos recipes collection. pull up a chair, we're finding readnoise and gain today. 🦋

---

✨ NAME ✨

vimos_ima_det_noise — detector noise, but make it imaging 📸

---

🌸 SYNOPSIS 🌸

esorex vimos_ima_det_noise [OPTIONS] FILE.sof

---

🎀 DESCRIPTION 🎀

vimos_ima_det_noise — it's the VIMOS recipe whose whole job is finding readnoise and gain. that's it. that's the mission. 💅

So basically it computes the readnoise and the gain for the vimos detectors, and it does that using two bias frames and two flat field frames. no cap, that's the whole recipe.

The program accepts the following files in the SOF:

• BIAS — a list of raw bias images 🖤
• FLAT_TWILIGHT — a list of raw flat images 🌤️
• MASTER_BPM — optional master bad pixel mask
• MASTER_CONF — optional master confidence map

so here's the tea: if a master bad pixel mask or a confidence map gets included, then the bad pixels will be flagged during the statistical analysis. 👀

---

💅 OPTIONS 💅

• --thresh <float> — rejection threshold in sigma above background (float; default: 5.0). The full name of this option for the EsoRex configuration file is vimos.vimos_ima_det_noise.thresh [default = 5.0]. ✨

heads up bestie: you can totally create a configuration file containing these options, along with suitable default values. just go check the details provided by the 'esorex --help' command. 🫶

An overview over the existing ESO pipelines can be found on the web page https://www.eso.org/sci/software/pipelines/.

Basic documentation about the EsoRex program can be found at the esorex (1) man page.

It is possible to call the pipelines from python using the python-cpl package. See https://packages.python.org/python-cpl/index.html for further information.

and that's the whole page, bestie. 💜 this was vimos_ima_det_noise version 4.1.7, living her best life as VIMOS_IMA_DET_NOISE(7) in the vimos recipes. go get that gain. you ate. periodt. 💅✨🎀
