Angle Functions

The functions below are useful for working with date and time. Many of these functions perform calculations while others perform conversions like DMS to degrees, and vice versa. The CImage class and others include some similar methods.

CalcAirmass	Calculates the airmass from celestial coordinates and time.
CalcSphAngle	Calculates the spherical angle between celestial or spherical coordinates.
DegToDms	Converts decimal degrees to a string containing degrees, minutes, and seconds.
DegToHms	Converts decimal degrees to a string containing hours, minutes, and seconds.
DmsToDeg	Converts an angle string containing degrees, minutes, and seconds to decimal degrees.
FormatAngle	Converts time in degrees, minutes, and seconds to a string.
FormatDmsStr	Formats an angle string containing various combinations of degrees, minutes, and seconds to a proper angle string.
HmsToDeg	Converts a time string containing hours, minutes, and seconds to decimal degrees.
HmsToHr	Converts a time string containing hours, minutes, and seconds to decimal hours.
HrToHms	Converts decimal hours to a time string containing hours, minutes, and seconds.
ParseDegrees	Converts a decimal degrees 3 numbers for hours, minutes, and seconds.
ParseDms	Converts a degrees string to degrees, minutes, and seconds.
ParseHms	Converts a time string to hours, minutes, and seconds.
