Pan-STARRS Module Library: pmReadout Struct Reference

A readout corresponds to an individual read of a cell (e.g., a single image as part of a video sequence, or one of multiple coadds). It contains the actual pixels used in analysis (along with mask and weight maps). When reading from a FITS file, the images are subimages (from CELL.TRIMSEC) of the pixels read from the appropriate HDU (at the FPA, chip or cell level). The readout also contains a list of bias sections (prescans or overscans, or otherwise), a summary of analysis tasks that have been performed, status flags, and the offsets used for reading a FITS file incrementally.

Data Fields
int	col0
	Column offset; non-zero if reading in columns incrementally.
int	row0
	Row offset; non-zero if reading in rows incrementally.
psImage *	image
	Imaging area of readout (corresponds to CELL.TRIMSEC region).
psImage *	mask
	Mask of input image (corresponds to CELL.TRIMSEC region).
psImage *	weight
	Weight of input image (corresponds to CELL.TRIMSEC region).
psList *	bias
	List of bias (prescan/overscan) images.
psMetadata *	analysis
	Readout-level analysis metadata.
pmCell *	parent
	Parent cell.
bool	process
	Do we bother about reading and working with this readout?
bool	file_exists
	Does the file for this readout exist (read case only)?
bool	data_exists
	Does the data for this readout exist (read case only)?
