SKYVIEW(1)

🦋 SKYVIEW(1) 🦋

okay so bestie, this is the General Commands Manual page for SkyView, and it's a whole ✨moment✨. buckle up, we're gonna get you generating images from remote databases like the main character you are 💅

---

🌈 NAME 🌈

SkyView — Image generation from a range of remote databases. periodt.

---

🌸 SYNOPSIS 🌸

skyview Survey=arg [key=arg ...]

---

💖 DESCRIPTION 💖

so basically, SkyView gives you a whole local SkyView system, like, on your own machine. your machine. your rules. iconic.

you can generate FITS, GIF, JPEG, ... images from major surveys in literally any geometry you want, resample and mosaic your own data, overlay grids and catalog positions, and — get this — create your own surveys. yes queen, build your own.

---

✨ OPTIONS ✨

heads up before we go any further: keys are NOT case sensitive, but values may be. so like, the key part is chill, the value part might not be. and when a value wants more than one thing, you separate them with a comma. easy.

valid keys include:

• Survey — a survey you want an image of (think WENSS, DSS). this one is Required, with no default, so don't come crying to me when it yells at you. want multiple surveys? comma-separate them. survey names are not case sensitive. oh and the user survey references data given in the UserFile argument 👀
• Settings — a list of one or more files to read settings from. lowkey important: file settings get processed after argument settings.

🎀 Keys that define the geometry of the output image. 🎀

• Position — the longitude and latitude of the center of the image. you can give it as coordinates or as a target name. [No default]
• Lon — the decimal longitude of the center of the image. [No default]
• Lat — the decimal latitude of the center of the image. [No default]

fr fr: either Position or Lon and Lat must be specified. you don't get to just… not say where. the sky is big bestie.

• Coordinates — a string giving the coordinate system and epoch (if it's needed), e.g. J, J2000, B1950, ICRS, Gal, H2010.438. [J]
• Equinox — epoch of equinox of coordinates. [2000]
• Projection — the three letter FITS WCS specification of the projection. [Tan]
• Scale — the pixels scale in degrees (may be one or two values). [survey dependent]
• Size — the size of the entire image in degrees. [scale*pixels]
• Pixels — the number of pixels in the image (may be one or two values). [300]
• Rotation — a rotation angle in the projection plane. [0]

ngl, generally you specify either scale or size but not both. pick a lane 💅

🦋 Keys that control optional graphical outputs 🦋

• Quicklook — the format you want for quicklook output. JPEG, GIF, BMP and TIFF are supported. and if you use another graphic keyword without specifying the format, it defaults to JPEG. generous of it honestly.
• Scaling — how the output pixel intensities get scaled. Linear, Log, Sqrt, HistEq are supported. [Linear]
• Min — set all smaller pixel values to this value before scaling.
• Max — set all larger pixel values to this value before scaling.
• RGB — create a three color overlay 🎨
• RGBSmooth — box smoothing for planes of RGBImages
• Invert — invert the color table response (or gray scale if no color lookup table is defined).
• LUT — load a color lookup table. see the users guide for lists of internal color tables and files supplied in the JAR. user generated color tables may also be used.
• Grid — plot a grid of the image or specified coordinate system as an image overlay.
• GridLabels — label the grid lines with the coordinate entries.
• PlotScale — scaling for plot symbols.
• PlotFontSize — size of plot text in points.
• PlotColor — color of plot graphics.

🔥 Catalog query keys 🔥

• Catalog — the names of the catalogs to be queried, or URLs that specify VOTable outputs.
• CatalogFile — the name of a file in which to print the IDs, positions, and pixel locations of the catalog entries found.
• CatalogRadius — a maximum radius from the center of the image for which catalog entries are desired.
• CatalogQualifier — a qualification on a column of the returned table (e.g. vmag<10).
• CatalogIDs — when plotting catalog positions, print the numeric ID of the catalog entry.

🧚 Keys that define the sampling used 🧚

• Sampler — the sampling algorithm to be used. NN, LI, Lanczos[n], Spline[n], Clip. [NN]
• Ebins — specification of sampling in energy dimension: e0,de,ne. [survey dependent for 3-d surveys]
  • e0 is the starting offset of the first output bin.
  • de is the width of the output bins (relative to the input).
  • n is th number of output bins.

💜 Keys that set characteristics of the output FITS file 💜

• Output — the output file stem. [output]
• Compress — if specified, the output is gzip compressed.
• Float — if specified, the output is 4 byte rather than 8 byte real.
• NoFITS — a FITS file should not be produced.

🌸 Smoothing 🌸

• Smooth — a box size (or sizes for non-square box) for a box car smoothing.

🌈 Contours 🌈

• Contour — create a contour map overlay.
• ContourSmooth — smoothing to be applied to survey before contouring.

🍓 Keys that set where to look for survey and store survey data. 🍓

• XMLRoot — a directory of XML files that contain survey descriptions.
• SurveyManifest — overrides the name of the resource used to look for the survey manifest (normally included in JAR).
• SurveyXML — a file or files giving XML descriptions of surveys.
• UserFile — a file (or list of files) that defines the User survey. these are the actual survey images, not survey metadata. important distinction, don't mix them up.
• Cache — a directory (or comma delimited set of directories) where cached files are to be found. the first cache directory is where survey files used in this request will be saved.
• PurgeCache — delete any survey files downloaded in this request.

⭐ Keys that define the classes used for processing the request. ⭐

• Deedger — class that eliminates transitions at input image boundaries.
• SurveyFinder — class that loads and finds surveys given survey names/IDs.
• ImageFinder — class that finds images in a survey to use in a mosaic.
• PreProcessor — class[es] to process input images before resampling.
• Mosaicker — class that actually mosaics survey data to create output image.
• PostProcessor — class[es] that process the output image after mosaicking.

🫶 Keys that change the behavior of the process. 🫶

• ImageJ — leave an ImageJ session running with the generated images when finished.

🎀 Available surveys (including all aliases) 🎀

Okay so this is the part where the page just dumps the entire guest list on you 💅 and honestly? iconic. Every survey name plus every single alias that maps to it — spaces, dashes, underscores, colons, parentheses, all of it. You cannot freestyle this, bestie. The aliases are not guessable, so treat this as your lookup table and copy-paste like your life depends on it 🫶

Heads up: I'm keeping every name character-for-character exactly as written, including the double spaces in a couple of them (iras 100, iris 100 vibes). One wrong character and it's just not the same name, no cap 💀

Let's go, group by group 🌸

The low-frequency / 2MASS / AKARI girlies — look at all those spellings of the same thing, we love a flexible queen ✨

Bestie, that's the whole list. If you need one of these, scroll back up and copy it — do not try to recall it from memory, I am begging 🙏

And that's a wrap on SKYVIEW(1) 💖 this page is dated 17 Dec 2016 and it's the SKYVIEW(1) man page, so if you're citing it or checking the version, that's the tea ☕ go be great, you've got this 🌟
