CALC_DOP_ORB(1)

🌸 NAME 🌸

Hiii bestie, meet calc_dop_orb — and yes, the name is literally just calc_dop_orb. No secret alias, no ✨mysterious✨ second identity, the whole name is the name 💅

She lives in the User Commands section of the manual, filed under CALC_DOP_ORB(1), so if you went looking for her you already found her. Slay. 💖

🛰️ SYNOPSIS 🛰️

calc_dop_orb file.PRM  added.PRM  earth_radius  [doppler_centroid]

That's the whole vibe check right there: two PRM files, an earth radius, and an optional doppler centroid you may or may not hand over. ✨

💫 DESCRIPTION 💫

Okay so first, the lore you need: this program is part of GMTSAR. That's the context, she's a GMTSAR girlie fr fr 🫶

Now here's every single thing she takes, one by one, no skips:

• file.PRM — the input name of the PRM file. Your source of truth, your starting point.
• new.PRM — the output; the additional parameters get added to the PRM file.
  • earth_radius — input, you set the earth radius here. Pass 0 and she'll calculate the radius for you instead 🌍
  • [doppler_centroid] — no parameter at all → she calculates the doppler.
  • [doppler_centroid] — hand her a value (like 0.0) → she forces the doppler to that instead.

Lowkey note: the synopsis up top calls the second file added.PRM while the list below calls it new.PRM. Both names are literally what this page says — no cap, I'm not editing her, I'm just telling you what she wrote 💀

Then she runs it back, because she wants you to actually remember it. The usage line, iconic, exactly as she wrote it:

Usage: calc_dop_orb  file.PRM  added.PRM  earth_radius
[doppler_centroid]

And the same rundown one more time, because repetition is self-care and she is not skipping anything:

• file.PRM — input name of PRM file.
• new.PRM — output additional parameters to add to the PRM file.
  • earth_radius — input, set earth radius, 0 calculates radius.
  • [doppler_centroid] — no parameter calculates doppler.
  • [doppler_centroid] — use value (e.g. 0.0) to force doppler.

That's the whole page, bestie — go forth and process those PRM files 🦋
