write_fits_cut4
call write_fits_cut4( filename, np, pixel, signal , n_obs, serror[, header, coord, nside, order, units] )
name&dimensionality | kind | in/out | description |
---|---|---|---|
filename(LEN=filenamelen) | CHR | IN | FITS file to be read from, containing a cut sky map |
np | I4B | IN | number of pixels to be written in the file |
pixel(0:np-1) | I4B | IN | index of observed (or valid) pixels |
signal(0:np-1) | SP | IN | value of signal in each observed pixel |
n_obs(0:np-1) | I4B | IN | number of observation per pixel |
serror(0:np-1) | SP | IN | rms of signal in pixel, for white noise,
this is
![]() |
header(LEN=80)(1:) (OPTIONAL) | CHR | IN | FITS extension header |
coord(LEN=1) (OPTIONAL) | CHR | IN | astrophysical coordinates ('C' or 'Q' Celestial/eQuatorial, 'G' for Galactic, 'E' for Ecliptic) |
nside (OPTIONAL) | I4B | IN | HEALPix resolution parameter of data set |
order (OPTIONAL) | I4B | IN | HEALPix ordering scheme, 1: RING, 2: NESTED |
header(LEN=80) (OPTIONAL) | CHR | IN | FITS header to be included in the FITS file |
units(LEN=20) (OPTIONAL) | CHR | IN | maps units (applies only to Signal and Serror) |
Note: the information relative to Nside, Order and Coord has to be given, either thru these keyword or via the FITS Header. |
