getObjectList

public Map[] getObjectList(String sortKey)

Returns a sorted HashMap array with the list of the object parameters. The sorting key is specified as the method's argument. The possible keys are as follows:

• xc - centroid x-coordinate
• yc - centroid y-coordinate
• mag - instrumental magnitude
• sharpness - object's sharpness
• E - elongation
• Theta_deg - object's inclination in degrees
• area - # of pixels in the search box within the allowed data range
• sky - instrumental sky value: average of the pixels contributed to the area

Parameters:

sortKey - String specifying the sorting key.

Returns:

sorted HashMap array.

freeCpp

public void freeCpp()
