✨ FORS_RESAMPLE ✨

okay bestie, gather round, because we're talking about fors_resample from the FORS recipes gang, and honestly? she's giving glow-up energy 💅 This is the FORS_RESAMPLE(7) page, so let's get into it.

💖 NAME 💖

fors_resample — resample input spectra at constant wavelength step 🌈

🎀 SYNOPSIS 🎀

esorex fors_resample [OPTIONS] FILE.sof

🦋 DESCRIPTION 🦋

so basically, this recipe resamples spatially rectified spectra at a constant wavelength step. no cap. 🌸

The input frames come from either the recipe fors_extract_slits (that's for MOS/MXU multi slit exposures), or from the recipes fors_remove_bias and fors_flatfield (that's for LSS or long-slit-like MOS/MXU data). And listen — only in the case of LSS or LSS-like data is the SLIT_LOCATION table required in input. Bestie, please refer to the FORS Pipeline User´s Manual for more deets 📖

In the table below, the MXU acronym can also be read as MOS and LSS, SCI can be read as STD, and SCIENCE as STANDARD. iykyk 💫

Input files:

  • LAMP_UNBIAS_MXU or SCIENCE_UNBIAS_MXU or SCIENCE_UNFLAT_MXU or RECTIFIED_LAMP_MXU or RECTIFIED_ALL_SCI_MXU or RECTIFIED_SCI_MXU or RECTIFIED_SKY_SCI_MXU — DO category, Calib — Frame to resample — Required: Y
  • DISP_COEFF_MXU or DISP_COEFF_SCI_MXU — DO category, Calib — Dispersion coefficients — Required: Y
  • SLIT_LOCATION_MXU — DO category, Calib — Slit location table — Required: Y
  • GRISM_TABLE — DO category, Calib — Grism table — Required: .

Output files:

  • MAPPED_LAMP_MXU or MAPPED_ALL_SCI_MXU or MAPPED_SCI_MXU or MAPPED_SKY_SCI_MXU — Data type, FITS image — Resampled spectra ✨

🔥 OPTIONS 🔥

  • --dispersion <float> — Expected spectral dispersion (Angstrom/pixel) (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_resample.dispersion [default = 0.0]. 🌈
  • --startwavelength <float> — Start wavelength in spectral extraction (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_resample.startwavelength [default = 0.0]. 🎀
  • --endwavelength <float> — End wavelength in spectral extraction (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_resample.endwavelength [default = 0.0]. 💜
  • --flux <bool> — Apply flux conservation (bool; default: True). The full name of this option for the EsoRex configuration file is fors.fors_resample.flux [default = True]. 👑
Not me reminding you that it's 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. fr fr.

and that's the whole page, bestie!! 💅 this one's fors_resample 5.5.7, part of the fors recipes, and the footer vibes were FORS_RESAMPLE(7) with fors_resample at version 5.5.7 — periodt. go forth and resample, you absolute icon 👑✨
