natgrid_params(3NCARG)

💖 natgrid_params — the NCAR Graphics manual, but make it a group chat 💖

okay bestie, welcome to natgrid_params(3NCARG), a page from the NCAR GRAPHICS manual. yes it's a Fortran-flavoured situation from the late 90s, and yes it still ate. 🫶

✨ NAME ✨

natgrid_params — this doc spills the tea on every single internal parameter of Natgrid. all of them. no crumbs left. 👑

🌸 DESCRIPTION 🌸

so here's the vibe: every entry down there gives you the name of the parameter, its Fortran type (if you're in C, just use the obvious equivalent, iykyk), its default value, and a lil description of what it actually does. that's it. that's the whole format. iconic. 💅

• ADF — Integer — 0 — this one flags whether the data file of algorithmic information gets produced so you can display it with nnalg. check the alg parameter for the deets. (0=no; 1=yes).
• ALG — Character — nnalg.dat — the file name that gets fed as input to the algorithmic display tool nnalg (peep the adf parameter too). 💖
• ASC — Integer — 1 — flags whether automatic scaling is allowed (0 = no; 1 = yes). let it cook or don't, your call.
• bI — Real — 1.5 — a tautness factor. the more bI goes up, the more the effect of the gradient estimates goes up. that's the whole relationship. 🦋
• bJ — Real — 7.0 — another tautness factor, but this one's a hater: as bJ increases, the breadth of the region affected by the gradient estimates gets smaller. ✨
• EXT — Integer — 1 — flags whether extrapolation is allowed outside the convex hull (0=no; 1=yes).
• HOR — Real — 0.1*(extent of X output grid) — specifies how much horizontal overlap gets included outside of the current region when doing subblocking. 🌈
• IGR — Integer — 0 — flag for whether gradient estimates are to be computed (1=yes; 0=no).
• MAGX — Real — 1.0 — scale factor for X coordinate input values. 🎀
• MAGY — Real — 1.0 — scale factor for Y coordinate input values. 🎀
• MAGZ — Real — 1.0 — scale factor for Z coordinate input values. 🎀 (yes bestie, all three of them are 1.0 by default, the symmetry is giving ✨)
• MDM — Integer — 10 — the max number of informational messages about duplicate point culls. it's a whole limit, respect it.
• NON — Integer — 0 — flags whether interpolated values are allowed to be negative (0=yes; 1=no). read that one twice, the numbers are backwards-feeling but that's literally what it says. 💀
• NUL — Real — 0.0 — the value used on output for points outside of the convex hull when extrapolation is not allowed.
• RAD — Integer — 0 — flags if slopes and aspects come back in radians or degrees (1=radians; 0=degrees).
• SDI — Integer — 0 — flags if slopes and aspects are computed (0=no; 1=yes).
• UPD — Integer — 1 — flags if the output array goes south to north or north to south (0=north to south; 1=south to north). direction girlies rise 🧚
• VER — Real — 0.1*(extent of Y output grid) — specifies how much vertical overlap gets included outside of the current region when doing subblocking. 🍓
• XAS — Real — 1.0 — holds the scale value for automatic scaling of X input values from the most recent interpolation call. ⚠️ retrieval only, babe — don't try to set it.
• YAS — Real — 1.0 — holds the scale value for automatic scaling of Y input values from the most recent interpolation call. ⚠️ retrieval only.
• ZAS — Real — 1.0 — holds the scale value for automatic scaling of Z input values from the most recent interpolation call. ⚠️ retrieval only. 💜

🌟 so like, this page is from the UNIX manual, dated March 1997-1998, and the source/version tag is natgrid_params(3NCARG). that's the whole footer, bestie — consider yourself signed off on. slay, stay interpolating, and don't forget the retrieval-only ones. periodt. 💅✨🦋
