HAWKI_DETECTOR_NOISE(7)

💖 HAWKI_DETECTOR_NOISE 💖

okay bestie, gather round, because this is the hawki_detector_noise page from the hawki recipes manual and she is lowkey iconic. it's giving "detector calibration but make it cute". let's go 🫶

✨ NAME ✨

hawki_detector_noise — the HAWKI detector noise recipe. yes queen, she's the one who figures out your readnoise and gain 💅

---

🌸 SYNOPSIS 🌸

esorex hawki_detector_noise [OPTIONS] FILE.sof

---

🦋 DESCRIPTION 🦋

hawki_detector_noise — the HAWKI recipe that finds your readnoise and your gain. periodt.

So basically: it computes the readnoise and gain for the hawki detectors using two dark frames and two flat field frames. and no cap, both of them have to have been exposed with NDIT=1. that's not a suggestion bestie, that's the vibe. ⭐

the program accepts the following files in the SOF:

• DARK — a list of raw dark images 🌑
• FLAT_TWILIGHT — a list of raw flat images 🕯️
• MASTER_BPM — optional master bad pixel mask, or
• MASTER_CONF — optional master confidence map

and here's the tea 🍓: if a master bad pixel mask or a confidence map is included, then thebad pixels will be flagged during the statistical analysis. she said "i see you, bad pixel, and i'm putting a flag on you". 🙈

---

💅 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 hawki.hawki_detector_noise.thresh [default = 5.0].

---

✨ side note bestie ✨ — you can absolutely make a configuration file holding these options with your own suitable default values. wanna know how? please refer to the details provided by the esorex --help command. she's got you. 🎀

🌈 SEE ALSO 🌈

the full documentation for the hawki pipeline can be downloaded as a PDF file using the following URL:

ftp://ftp.eso.org/pub/dfs/pipelines/hawki/hawki-pipeline-manual-2.4.11.pdf

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, babe ✨ she came from the hawki recipes manual, version 2.4.11, page hawki_detector_noise in section 7 — HAWKI_DETECTOR_NOISE(7) if you're being formal. now go compute that readnoise and gain, you absolute icon. slay 💖🌸🦋🎀🌈⭐💅
