Note: If the previous user has not been using the Mini-Mosaic camera, but rather the old ``S2KB" CCD, you should first do an obsetup. Normally this will not be needed. However, we are mentioning this command, as it may be needed during the short transitional phase as Mini-Mosaic replaces the old WIYN imager.
At the very beginning of your observing run, you should clean off all of the previous observer's images and files, and reinitialize all of the parameters to their default values. You or the instrument assistant can accomplish this by the following:
The reason for the above procedure is that you cannot have IRAF running during an obsinit or parameters will not be correctly reset. Make sure that you have logged out of each IRAF window before running obsinit.
An example of using obsinit is given in Figure 10. Note that the user has the option of selecting whether CNTL-z or CNTL-d will be the default for an end-of-file command; the former is the standard at NOAO, but the latter is the standard at many other places. Finally, note that it is possible to run obsinit WITHOUT deleting any files or images! If you simply wish to set the ARCON parameters back to their default values, you may run this in the middle of your observing run without losing any files.
