UVES_CAL_CD_ALIGN(7)

💖 uves_cal_cd_align — a whole manual page, bestie 💖

okay so this is the manual page for uves_cal_cd_align, and it lives in section 7 of the manual (that's the "miscellaneous / recipes" shelf, iykyk). It's part of the uves recipes crew. Sit down, get a snack, we're doing this properly. 🍓

✨ NAME ✨

uves_cal_cd_align — Measures the reproducability of the cross disperser positioning

(yes, "reproducability", that's literally how it's spelled here, we don't fix it, we respect it 💅)

---

🌈 SYNOPSIS 🌈

esorex uves_cal_cd_align [OPTIONS] FILE.sof

that's it. that's the whole invocation. esorex plus the recipe name plus your options plus a .sof file. slay.

---

🦋 DESCRIPTION 🦋

So here's the vibe: you hand this recipe two input frames (CD_ALIGN_xxx where xxx = BLUE or RED) and those frames contain only one echelle order. What does the recipe do with them? It measures the shift in the cross-dispersion direction of that order. That's the whole gig. 🎯

heads up for the RED girlies: for RED input frames, only the lower chip is processed. no cap.

The recipe then produces a CD_ALIGN_TABLE_xxxx (with xxxx = BLUE or REDL) and it's got columns, bestie, and every single one of them matters:

• X — Column number
• YCENi — Centroid from Gaussian fit (for i = 1,2)
• SIGMAi — Stdev from Gaussian fit
• BACKi — Constant background from Gaussian fit
• NORMi — Normalization constant from Gaussian fit
• YDIFF — Difference YCEN2 - YCEN1 of centroid positions

and the QC-parameters ESO.QC.YDIFF(AVG|MED|RMS), which are the average, median and root-mean-square of the y-shift, respectively. three little stats, all grown up. 👑

💅 OPTIONS 💅

One bullet per option, exactly as the universe intended. Go off:

• --debug <bool> — Whether or not to save intermediate results to local directory (bool; default: False). The full name of this option for the EsoRex configuration file is uves.debug [default = False].
• --plotter <str> — Any plots produced by the recipe are redirected to the command specified by this parameter. The plotting command must contain the substring ´gnuplot´ and must be able to parse gnuplot syntax on its standard input. Valid examples of such a command may include ´gnuplot -persist´ and ´cat > mygnuplot$$.gp´. A finer control of the plotting options can be obtained by writing an executable script, e.g. my_gnuplot.pl, that executes gnuplot after setting the desired gnuplot options (e.g. set terminal pslatex color). To turn off plotting, set this parameter to ´no´ (str; default: ´no´). The full name of this option for the EsoRex configuration file is uves.plotter [default = no].
• --process_chip <str> — For RED arm data process the redl, redu, or both chip(s) (str; default: ´both´). The full name of this option for the EsoRex configuration file is uves.process_chip [default = both].
• --steps <int> — Step size in pixels (int; default: 100). The full name of this option for the EsoRex configuration file is uves_cal_cd_align.steps [default = 100].
• --window <int> — The half window height used for Gaussian fitting (int; default: 50). The full name of this option for the EsoRex configuration file is uves_cal_cd_align.window [default = 50].
• --xborder <int> — Exclude a border region of this size (pixels) (int; default: 200). The full name of this option for the EsoRex configuration file is uves_cal_cd_align.xborder [default = 200].

🫶 btw bestie, note that it is possible to create a configuration file containing these options, along with suitable default values. Please refer to the details provided by the 'esorex --help' command. it's giving self-sufficient. periodt.

and that's the whole page, bestie!! 🧚 this was uves_cal_cd_align version 6.1.8, served fresh from the uves recipes, and if you made it this far you are genuinely the main character. mwah. 💜
