1. GetImage now supports the new photometric calibrations of the DSS. The calibrations are extracted into binary table extensions of FITS files containing images extracted from the DSS. See Using the New Features for details on using GetImage with the new photometric calibrations.

2. Getimage now has a well-defined scheme for accessing the DSS mounted in a CD-ROM jukebox. See Using the New Features for details on how to setup GetImage for use with a CD-ROM jukebox.

3. Input coordinates are now accepted by GetImage which have 24 in the hours field of right ascension and 60 in the minutes and seconds fields of right ascension and arcminutes and arcseconds fields of declination.

4. GetImage will now never output coordinates which have 24 in the hours field of right ascension and 60 in the minutes and seconds fields of right ascension and arcminutes and arcseconds fields of declination.

5. A bug which caused images extracted from the tops of some plates to be "skewed" has been corrected. This bug was actually corrected in patch "a" to version 1.3.

6. A bug which caused erroneous change of case of directory path names has been corrected.

7. A bug which caused erroneous detection of undefined plate list environment variables has been corrected.

8. A bug which caused erroneous allocation of 4 bytes for each image pixel has been corrected to now properly allocae 2 bytes for each pixel, so memory allocation for each extracted image is now cut in half.

1. The documentation for GetImage has not yet been updated from Version 1.3. The documentation on this WWW page is the only documentation currently available for information specific to Version 2.0 of GetImage.

2. Some modifications planned for GetImage 2.0 have not yet been completed. These include writing additional informational keywords to extracted image headers and enhancements to command line options.

GetImage users do not need to independently obtain the CFITSIO package. CFITSIO is distributed with the GetImage software for the express purpose of building the GetImage executable. The GetImage build procedures will automatically create the required CFITSIO library.

• Photometric Calibration Support

  There are two components required in order for GetImage 2.0 to support the new photometric calibrations:

  The Calibration FITS Files

  They are available at DSS photometric calibrations. There are three calibration files, one for each of the primary photographic surveys in the DSS. To install the calibration files, copy them to the headers directory below the GetImage installation directory.

  A New Plate List File

  The new version of the plate list file specifies for GetImage which calibration FITS file is appropriate for each plate. This file, called locomp20.lis, is automatically provided with the GetImage 2.0 release.

  There are two command line options associated with the GetImage calibration interface: +cal and +nocal. If +cal is present, then extracted FITS images will contain the available calibration data. If +nocal is present, then extracted FITS images will not contain any calibration data. +cal is the default.

• CD-ROM Jukebox Support

  Past versions of GetImage have included experimental schemes for accessing the DSS mounted in a CD-ROM jukebox. With version 2.0, GetImage now has a well-defined scheme for accessing the DSS mounted in a CD-ROM jukebox.

  The new scheme utilizes a path-list file to specify the location of each disc of the DSS in a jukebox. There is one record in the path-list file for each disc in the DSS. Each record consists of two fields. The first field is the volume label of the disc, and the second field is the path in the file system to the disc mounted in the jukebox. With your browser set to download as file, a sample path-list file may be downloaded at sample path-list file.

  To set up GetImage to extract images from the DSS mounted in a CD-ROM jukebox, edit the sample path-list file as appropriate for your system, and place the file into the headers directory below the GetImage installation directory. By default, the path-list file should be named "jukebox_paths.lis".

  The DSS may then be accessed from the jukebox by invoking GetImage with the "+jukebox" option. If an alternate name was chosen for the path-list file, it may be accessed by specifying the file name on the GetImage command line: "+jukebox file.name".
