Options to the HCompress compression algorithm when the compression includes quantization. When compressing tables and images using the HCompress algorithm, including quantization, users can control how exactly the compression and quantization are perfomed. When reading compressed FITS files, these options will be set automatically based on the header values recorded in the compressed HDU.

Use the more intuitively namedFitsKeyclass instead.

Otherwise, it is similar toStandardIHierarchKeyFormatter. Its use over the more standard formatter is discouraged.(for internal use) This class should not have public visibility.

No longer used within the FITS package itself. If you do attempt to use it with the deprecated APIs, beware that no data will be filled into the buffer of this object ever by the library, although its length and position fields may be updated to pretend as if the buffer were always hall full / half available...This class should not be exposed in the public API and is intended for internal use only in ASCII tables. Also, it may have overlapping functionality with other classes, which should probably be eliminated for simplicity's sake (and thus less chance of nasty bugs).This class should not be exposed in the public API and is intended for internal use only in ASCII tables.

It can be confusing since it is not clear if it refers to array element types used in FITS storage or on the java side when using the older array access, or if it refers to the class of entries in the main table, which may be heap pointers. It is also distinct fromBinaryTable.ColumnDesc.getElementClass(), which returns the boxed type used byBinaryTable.get(int, int)orBinaryTable.set(int, int, Object).(for internal use) UseBinaryTable.ColumnDesc.getEntryShape()instead. Not useful to users since it returns the dimensions of the primitive storage types, which is not always the dimension of table entries on the Java side.(for internal use) This method should be private in the future.(for internal use) It may be reduced to private visibility in the future.

Returns the integer value that represents missing data (null) in the quantized representation.QuantizeOption.setBNull(Integer)controls this feature automatically as needed. Sets whether we should expect the floating-point data to containnullvalues (normally NaNs).It is strongly discouraged to treat 0.0 values as special. FITS only recognises NaN as a special floating-point value marking missing data. All other floating point values are considered valid measurements.The use of null values other thanNaNfor floating-point data types is not standard in FITS. You should therefore avoid using this method to change it. Returns the floating-point value that indicates anulldatum in the image before quantization is applied. Normally, the FITS standard is that NaN values indicatenullvalues in floating-point images. While this class allows using other values also, they are not recommended since they are not supported by FITS in a standard way.UseBasicHDU.verifyIntegrity()instead when appropriate. It's not particularly useful since integrity checking does not use or require knowledge of this sum. May be removed from future releases.useFits.getNumberOfHDUs()insteadUseFits(InputStream)constructor instead. We will remove this method in the future.Use try-with-resources constructs in Java 8+ instead.This method is poorly conceived as we cannot really read FITS from just anyArrayDataInputbut only those, which utilizeFitsDecoderto convert Java types to FITS binary format, such asFitsInputStreamorFitsFile(or else a wrappedDataInputStream). As such, this method is inherently unsafe as it can be used to parse FITS content iscorrectly. It will be removed from the public API in a future major release. Set the data stream to be used for future input.The meaning of size of ambiguous. UseFits.getNumberOfHDUs()instead. Note size() will read the input file/stream to the EOF before returning the number of HDUs whichFits.getNumberOfHDUs()does not. If you wish to duplicate this behavior and ensure that the input has been exhausted before getting the number of HDUs then use the sequence:read(); getNumberOfHDUs();This method is poorly conceived as we cannot really write FITS to just anyDataOutputbut only to specificArrayDataOutput, which utilizeFitsEncoderto convert Java types to FITS binary format, such asFitsOutputStreamorFitsFile(or else a wrappedDataOutputStream). As such, this method is inherently unsafe as it can be used to create unreadable FITS files. It will be removed from a future major release. Use one of the more appropriate otherwrite()methods instead. Writes the contents to an external file or stream. The file or stream remains open and it is up to the caller to close it as appropriate.(for internal use) Will reduce visibility in the futureUseFits.makeHDU(Object)instead (this method may either be migrated toFitsentirely or else have visibility reduced to the package level).(for internal use)/ Will reduce visibility in the futureUseFits.makeHDU(Object)instead (will removed in the future.

Find the card associated with a given key.UseFitsKey(String, VALUE, String)instead.(for internal use) Creates a array of generic FITS header keys.

Returns the original size of the header in the stream from which it was read.We should never use indexed access to the header. This function will be removed in 2.0.(for internal use) Normally we either want to write a Java object to FITS (in which case we have the dataand want to make a header for it), or we read some data from a FITS input.

Header.rewriteable(), so users should not call this method unless they do not intend toHeader.rewrite()this header into the original FITS.Use the saferHeader.setBitpix(Bitpix)instead.(for internall use) Visibility will be reduced to the package level in the future.Not recommended as it may violate the FITS standart for 'fixed-format' header entries, and make our FITS files unreadable by software that expects strict adherence to the standard.
