Problems?

  Please email pmassey@noao.edu any discrepancies you find between this manual and reality; please report any problems by writing a service request (see instructions at your telescope); suggestions for ICE improvements may be made on your run evaluation form. Some of the items that we feel may cause some confusion or difficulties at present include:

  1. If you have displayed an image and then reduced the size of the image by running ccdproc on it, you will get crazy results if you run imexamine on this image without first explicitly redisplaying it.

  2. If you inadvertently use the wrong ``eof" character ( CNTL-z when you have defined CNTL-d as the eof or vice-versa) you may put IRAF into suspended animation. You can recover quickly by simply typing fg.

  3. If the SUN is rebooted, or the CCD controller has been turned off and back on, the following exposure may be very strange indeed. Do several ``zero" exposures to flush it out entirely

  4. Observers have occasional problems with Exabyte taping. We have found that in nearly all instances this has come from using non-computer grade tapes. If you have bought your Exabytes during a blue-light special at K-Mart, you may wish to consider purchasing real computer-grade tapes on the mountain.

  5. If you change a title during a sequence of exposures, the change may not propagate to subsequent exposures.

  6. If you are using the scan-table at the 4-m, the value of ``nrowscans" will be reset to ``1" (no scan) if you select a bias, dark, or focus frame. It will not be reset to the previous value when you next choose object. We recommend running the scan-table with ``query and set scan parameters?" to yes if you want to use the scan-table.
