CALIBRATION OF A COMPARATOR

THE OBJECTIVE IS TO DESCRIBE A PROCEDURE OF CALIBRATING A COMPARATOR USING TWO GRID PLATES WITH KNOWN STANDARD ERROR AND THEN COMPLETING A SIMULTANEOUS ADJUSTMENT CARRYING THE COMPARATOR AND GRID COORDINATES AS UNKNOWN PARAMETERS. THE PAPER ALSO DESCRIBES A METHOD OF OBTAINING THE STANDARD ERROR OF THE PHOTO COORDINATES USING THE STANDARD ERROR OF THE GRID COORDINATES. IN THE EXISTING LITERATURE ON THIS SUBJECT NO METHOD OF CORRECTING THE ERRORS ORIGINATING IN GRID PLATES IS OFFERED. FURTHER, EXISTING LITERATURE DESCRIBE ONLY PROCEDURES OF OBTAINING THE STANDARD ERROR OF THE PRECISION OF OBSERVATIONS, BUT NOT THE STANDARD ERROR OF THE PHOTO COORDINATES. /AUTHOR/
