C.2 Retrieving Observation Logs

---

You can retrieve observation log files for data taken after October 20, 1994 from the HST Archive using StarView as described in chapter 1 of the HST Introduction. Unlike science data, which generally has a one-year proprietary period, observation log files become public as soon as they are archived.

The easiest way to get OMS files through StarView is to identify the observation of interest and proceed with your request as described in chapter 1 of the HST Introduction, until you reach the "HST Retrieval Configurations Options" screen, reproduced in figure C.3. You can then check the Observation Log Files box, along with any other desired boxes, and continue with your request. StarView will then deliver the associated observation log files.

For observations logged between October 1994 to August 1995, you will be delivered the cmi, cmj, and cmh files in FITS form (e.g., _cmi.fits). Observations archived from August 1995 to February 1997 will return _jif.fits and _jit.fits files. These, and the earlier FITS files can be worked with as such, or converted to their GEIS counterparts via the STSDAS strfits task. However, as of February 1997, the _jif.fits and _jit.fits files are standard FITS files with extensions and cannot be converted to GEIS.
