Inputs
file - Information file to be read.
Optional Input Parameters
Keyword Input Parameters
Outputs
object - Name of object measured (string)
firstfile - Name of file (may include chip id) of first measure (string)
nobs - Number of observations of this object in this dataset (int)
rmag - Average R magnitude of object (float)
99.9 means no good magnitude could be measured
rmagerr - Error on R magnitude of object (float)
rate - Rate of motion, arcsec/hour (float)
angle - Direction of motion, E from N, degrees (float)
arc - Arclength of this measurement, arcsec (float)
dt - Time span of this measurement, hours (float)
vsig - velocity dispersion of measurements, sigma of "/hr (float)
valid only when nobs>2
sel - Solar elongation, degrees (int)
dist - Approximate distance to object, AU (float)
this assumes object is precisely at opposition.
nobj - Total number of obects (0 if file is empty or missing).
