SKYVIEW(1) General Commands Manual SKYVIEW(1)

NAME

SkyView - Image generation from a range of remote databases

SYNOPSIS

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

DESCRIPTION

SkyView provides users with a local SkyView system on their own machines. Users can generate FITS, GIF, JPEG, ... images from major surveys in any requested geometry, resample and mosaic their own data, overlay grids and catalog positions, and create their own surveys.

OPTIONS

Keys are not case sensitive but values may be. Values specifying more than one value use a comma as a separator. Valid keys include:
Survey
A survey for which an image is requested (e.g, WENSS, DSS) (Required, with no default.) To request multiple surveys, separate them by commas. Survey names are not case sensitive. The 'user' survey references data given in the UserFile argument
Settings
A list of one or more files from which settings are read. File settings are processed after argument settings.

Keys that define the geometry of the output image.

Position
The longitude and latitude of the center of the image. This may be given 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]

Either Position or Lon and Lat must be specified.

Coordinates
A string giving the coordinate system and epoch (if required) used, 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]

Generally you specify either scale or size but not both.

Pixels
The number of pixels in the image (may be one or two values) [300]
Rotation
A rotation angle in the projection plane [0]

Keys that control optional graphical outputs

Quicklook
The format desired for quicklook output. JPEG, GIF, BMP and TIFF are supported. If another graphic keyword is used without specifying the format it defaults to JPEG.
Scaling
How the output pixel intensities are to be 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.
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.
