Determines whether the specified Object is equal to the current Object.

double fDistanceEq(ra1,dec1,ra2,dec2) returns distance in ArcMinutes between two points.

double fDistanceLatLon(lat1,lon1,lat2,lon2) returns distance in ArcMinutes between two points.

double fDistanceXyz(x1,y1,z1,x2,y2,z2) returns distance in ArcMinutes between two points.

fHtmCoverCircleEq(ra,dec,radiusArcMin) returns a trixel table (a list) covering
the circle centered at that J2000 ra,dec, within that arc-minute radius.
A trixel table is a list of HtmStart,HtmStop pairs that describe
the HTM triangles (all points of a triangle are between its HtmStart and HtmStop.

fHtmCoverCircleLatLon(ra,dec,radiusArcMin) returns a trixel table (a list) covering
the circle centered at that lat,lon, within that arc-minute radius.
A trixel table is a list of HtmIDStart,HtmIDEnd pairs that describe
the HTM triangles (all points of a triangle are between its HtmIDStart and HtmIDEnd.

fHtmCoverCircleXyz(x,y,z,radiusArcMin) returns a trixel table (a list) covering
the circle centered at that x,y,z, within that arc-minute radius.
A trixel table is a list of HtmIDStart,HtmIDEnd pairs that describe
the HTM triangles (all points of a triangle are between its HtmIDStart and HtmIDEnd.

fHtmCoverList(regionspec) returns a list of HtmID's that describe the HTM triangles covering the region.

fHtmCoverRegion(region) returns a list of HtmStart,HtmStop pairs
that describe the HTM triangles covering the region.

fHtmCoverRegionAdvanced(region) returns a list of HtmStart,HtmStop pairs
that describe the HTM triangles covering the region. Inner and Outer triangles. are treated separately.

fHtmCoverRegionError(coverspec) returns diagnostic message appropriate for a bad region string or "OK" if there are no errors

fHtmCoverRegionSelect(regionspec) returns a the qualified list of HtmIDStart,HtmIDEnd pairs
that describe the level 20 trixels covering the region.

fHtmEq(ra,dec) returns the 20-deep HtmID of the given equatorial point.
There are no error cases. all RA, folded to [0..360] and dec to [-90...90]

XyzTable(x,y,z) fHtmEqToXyz(ra, dec) converts an equitorial point to a table with one row containing the cartesian point (x,y,z)

fHtmGetCenterPoint(HtmID) converts an HTM triangle ID to an (x,y,z) vector of the HTM triangle centerpoint. and returns that vector as the only row of a table.

fHtmGetCornerPoints(HtmID) converts an HTM triangle ID to an table of three (x,y,z) vectors of the HTM triangle corners.

fHtmGetString(HtmID) returns varchar(max)a string describing the HtmID

fHtm(lat,lon) returns the 20-deep HtmID of the given location. There are no error cases. all RA, folded to [0..360] and dec to [0...90]

XyzTable(x,y,z) fHtmLatLonToXyz(lat, lon) converts an lat,lon point to a table with one row containing the cartesian point (x,y,z)

fHtmRegionToTable(region) converts a region definiton a table of halfspaces

fHtmVersion() returns the version number of this htm library as a string

fHtmXyz(x,y,z) returns the 20-deep HtmID of the given cartesian point. There are no error cases. All vectors are nomalized and 0,0,0 maps to 1,0,0

EqTable(ra, dec) fHtmXyzToEq(x,y,z) converts the cartesian point (x,y,z) to a table with one row containing the equivalent equitorial (ra,dec) point

LatLonTable(lat,lon) fHtmXyzToLatLon(x,y,z) converts the cartesian point (x,y,z) to a table with one row containing the equivalent lat,lon point

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Serves as a hash function for a particular type.

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

Returns a String that represents the current Object.
