Description
Convert Right Ascension and declination from decimal to sexigesimal units
Usage
1
radec(ra, dec, hours=F)
Arguments
ra
Right Ascension, in degrees, scalar or vector
dec
declination, in degrees, scalar or vector
hours
if =TRUE, then the input right ascension should be specified in decimal hours instead of degrees (default = FALSE)
Details
The conversion is to sexigesimal hours for RA, and sexigesimal degrees for declination.
Value
A list with components:
ihr
Right Ascension hours, integer scalar or vector
imin
Right Ascension minutes, integer scalar or vector
xsec
Right Ascension seconds, real scalar or vector
ideg
declination degrees, integer scalar or vector
imn
declination degrees, integer scalar or vector
xsc
declination degrees, real scalar or vector
