Class CCDGeometryConstants

java.lang.Object

org.lsst.ccs.utilities.ccd.CCDGeometryConstants

public final class CCDGeometryConstants
extends Object

An object that defines CCD specific geometrical constants. We assume that all the Segments within a CCD are described by the same SegmentGeometryConstraint object, i.e. they have the same geometry.

Constructor Detail

CCDGeometryConstants

public CCDGeometryConstants(SegmentGeometryConstants segmentGeometryConstants,
                            double parallelEdge,
                            double serialEdge)

Build a CCDGemetryConstants object describing a CCD geometry constants. A CCD contains 16 segments whose geometry constants are defined by the provided SegmentGeometryConstants. These Segments are all side by side, 2 in the parallel direction and 8 in the serial direction. The Segments don't cover all the CCD area; there is an edge along the CCD sides. The parallel edges have the same dimension as do the edges along the serial direction.

Parameters:

segmentGeometryConstants - The SegmentGeometryConstants object describing each Segment geometry constants.

parallelEdge - The CCD edge along each parallel side in pixels

serialEdge - The CCD edge along each serial side in pixels

Method Detail

getSegmentParallelActiveSize

public int getSegmentParallelActiveSize()

Get the Segment parallel active size in pixels. This corresponds to Designator variable "dimv" in Table 8 of LCA-13501

Returns:

The Segment parallel active size.

getSegmentSerialActiveSize

public int getSegmentSerialActiveSize()

Get the Segment serial active size in pixels. This corresponds to Designator variable "dimh" in Table 8 of LCA-13501

Returns:

The Segment serial active size.

getSegmentSerialPrescanSize

public int getSegmentSerialPrescanSize()

Get the Segment serial prescan size in pixels. This corresponds to Designator variable "preh" in Table 12 of LCA-13501

Returns:

The Segment serial active size.

getActiveAreaParallelSize

public int getActiveAreaParallelSize()

The CCD dimension, in pixels, of the active area along the parallel direction. This is the segments parallel size multiplied by the number of segments laid out along the parallel direction. This corresponds to Designator variable "ccdax" in Table 8 of LCA-13501

Returns:

The CCD dimension, in pixels, of the active area along the parallel direction.

getActiveAreaSerialSize

public int getActiveAreaSerialSize()

The CCD dimension, in pixels, of the active area along the serial direction. This is the segments serial size multiplied by the number of segments laid out along the serial direction. This corresponds to Designator variable "ccday" in Table 8 of LCA-13501

Returns:

The CCD dimension, in pixels, of the active area along the serial direction.

getPhysicalAreaParallelSize

public int getPhysicalAreaParallelSize()

The CCD dimension, in pixels, of the physical area along the parallel direction. This is the sum of the segments parallel size multiplied by the number of segments laid out along the parallel direction and twice the CCD edge on the parallel direction. This corresponds to Designator variable "ccdpx" in Table 8 of LCA-13501

Returns:

The CCD dimension, in pixels, of the physical area along the parallel direction.

getPhysicalAreaSerialSize

public int getPhysicalAreaSerialSize()

The CCD dimension, in pixels, of the physical area along the serial direction. This is the sum of the segments serial size multiplied by the number of segments laid out along the serial direction and twice the CCD edge on the serial direction. This corresponds to Designator variable "ccdpy" in Table 8 of LCA-13501

Returns:

The CCD dimension, in pixels, of the physical area along the serial direction.
