hotspot reads a healpix map in FITS format and generates the following outputs: 1) a HEALPix map in FITS format which is zero everywhere, except at pixels which contain local extrema. These pixels have the same values as in the input map. 2) an ASCII file which lists the pixel numbers and values of maxima, and 3) an ASCII file which lists the pixel numbers and values of minima.
The facility can be used in both an interactive mode and a command mode, where command qualifiers are fed to the facility using an input file.
Note the following limitations: hotspot (and the toolkit neighbour finder which it uses) will only work on maps with .
hotspot runs in interactive mode.
When `filename' is present, hotspot enters the non-interactive mode and parses its inputs from the file `filename'. This has the following structure: the first entry is a qualifier which announces to the parser which input immediately follows. If this input is omitted in the input file, the parser assumes the default value shown below. If the equality sign is omitted, then the parser ignores the entry. In this way comments may also be included in the file. In this example, the file contains the following qualifiers:
hotspot reads in the map `map.fits' and generates an output map with name `pixlminmax.fits', and two ASCII files, `maxima.dat' and `minima.dat'.
- Initial release (HEALPix 0.90)
- Optional non-interactive operation. Proper FITS file support for input and output maps. (HEALPix 1.00)
