Slalib package

Gabriel wrote on Jun 18, 2009

Hi,

I need to access one of 'slalib' functions and I can't figure out how to do it. I've tried typing 'ecl> math', 'ecl> slalib', 'ecl> dtf2r', 'ecl> math.slalib' and more combinations of this, but nothing.

Thanks,
Cheers!

SLALIB is a library for compiled tasks. If all you want is to convert an RA to radians you can do it in the CL directly, e.g.


cl> =rad (ra * 15.0)
cl> = (ra * 15) * (PI / 180.)


These two are equivalent, there is also a complementary deg() function to convert to degrees. The CL handles sexagesimal directly, but you still need to multiple RA by 15 to get degrees as a floating point value.
