Welcome to the SoFiA Image Pipeline wiki!
Try typing which convert
. If you have karma/kvis installed (common for viewing HI radio cubes), then it may return:
/usr/local/karma/bin/convert
If this is the case, you need to find where ImageMagick is installed. If you installed with Homebrew the path may be something like:
/usr/local/Cellar/imagemagick/7.1.0-13/bin/convert
To create the combined image, add the correct path after the -m
option on the command line.
Naming scheme: <catalog_name>_cat.txt
Catalog contents:
- A commented header similar enough to SoFiA in that the data starts on line 18. (Will work to make this more flexible!)
- The following column names: id, name, ra, dec, x, y, x_min, y_min, x_max, y_max, rms.
- ra, dec are in decimal degrees
- x, y is the source center in pixels (float)
- x(y)_min(max) are the min/max in pixels of the source (int), used to determine if a larger figure should be retrieved for an individ source.
Naming scheme: <catalog_name>cubelets/<catalog_name>_mom0.fits
FITS header contents (these may be non-standard for mom0 maps, but are required for estimating meaningful column density contours):
- SPECSYS or VELREF to refer to the spectral coord system of the original data
- CTYPE3 to determine the spectral units of the original data
