Dec(double degrees)

Dec(double degrees, double sigmaDegrees)

Dec(double degrees, double mins, double secs)
Can pass in fractional degrees or minutes but will be held in normalised form with integer degrees and minutes plus fractional seconds.
10.2.1 Important change: previously the degrees part could be negative but min and sec were expected to be positive (as from a user dialogue).

Dec(double degrees, double mins, double secs, double sigmaDegrees)
Can pass in fractional degrees or minutes but will be held in normalised form with integer degrees and minutes plus fractional seconds.

Constructor Detail

Dec

public Dec(double degrees,
           double mins,
           double secs,
           double sigmaDegrees)

Can pass in fractional degrees or minutes but will be held in normalised form with integer degrees and minutes plus fractional seconds.
10.2.1 Important change: previously the degrees part could be negative but min and sec were expected to be positive (as from a user dialogue). BUT that will not work if the degrees part is zero. So...
VERY IMPORTANT: If the declination is negative every field in this constructor must be negative. Note that in a user dialogue (eg, in net.grelf.astro.StarChart) it can be different because each text field holds a String rather than a number so the sign is detectable on "-0".

Dec

public Dec(double degrees,
           double mins,
           double secs)
