Constructor Detail

FitsIntWriter

public FitsIntWriter(Image image,
                     org.lsst.ccs.utilities.ccd.Reb reb,
                     FitsIntWriter.FileNamer fileNamer)
              throws IOException

A FitsIntWriter constructor that can be called before the source meta-data is available. This must be followed by a call to completeInitialization.

Parameters:

image - The image for which data is to be written

reb - The corresponding REB

fileNamer - An interface for generating the names of the fits files to write

Throws:

IOException

FitsIntWriter

public FitsIntWriter(Source source,
                     org.lsst.ccs.utilities.ccd.Reb reb,
                     Map<String,org.lsst.ccs.utilities.image.HeaderSpecification> headerSpecifications,
                     FitsIntWriter.FileNamer fileNamer,
                     FitsIntWriter.PerCCDMetaDataProvider extraMetaDataProvider)
              throws DAQException,
                     IOException

Create a FitsIntWriter. If an exception is thrown by the constructor any files already created will be deleted.

Parameters:

source - The source for which data is to be written

reb - The corresponding REB

headerSpecifications - Fits header specifications

fileNamer - An interface for generating the names of the fits files to write

extraMetaDataProvider - Additional per-ccd fits header meta-data providers

Throws:

DAQException - If unable to obtain information about the source.

IOException - If an error occurs while writing the file
