force_newton.pro

Calculates the gravitational force from a particle distribution at a list of positions.

inertiatens.pro

Calculates the 2nd moment tensor (sometimes incorrectly referred to as the moment of inertia tensor) of a mass distribution specified by a list of particle positions.

jbimatch.pro

Determines the relative scaling of different images based on the measured output of the IRAF task MSCIMATCH.

match_nd.pro

For each arbitrarily-dimensioned point in one vector, determines the closest point in a second vector.

match_sph.pro

For each angular point in one vector, determines the closest angular match from another vector.

matchall_2d.pro

Determines which of a set of 2D coordinates are within a given distance from each of a vector of points.

matchall_nd.pro

Determines which of a set of coordinates of arbitratry dimension are a given distance from each of a vector of points.

matchall_sph.pro

Determines which of a set of angular coordinates on the sky (or on a sphere) are within a given angular distance from each of a vector of points.

mean_by_radaz.pro

Calculates the mean value of an image in bins of both radius and pie slices of azimuthal angle.

mm_dist.pro

Converts between distance modulus m-M and distance in parsecs.

potential_newton.pro

Calculates the gravitational potential from a particle distribution at a list of positions.

readdolphot.pro

Read the output of the DOLPHOT photometry package into easier-to- use data structures.

readfakedolphot.pro

Read the output of the DOLPHOT photometry package when run in artificial star mode into easier-to-use data structures.

shape_iterative.pro

Given a 3-dimensional distribution of points, determines the best ellipsoidal shape using particles in an interatively-defined ellipsoid (or ellipsoidal shell) of the same shape.

sixtyv.pro

Converts a vector of decimal numbers to sexigesimal (vector version of SIXTY in the astronomy library).

sky2xy.pro

Converts between sky coordinates and pixel coordinates of a FITS image using the WCSTOOLS sky2xy routine.

velframe.pro

Converts radial velocities between Local Standard of Rest, Heliocentric and Galactocentric velocity frames.

xy2sky.pro

Converts between pixel coordinates of a FITS image and sky coordinates using the WCSTOOLS xy2sky routine.
