Starview & DADS (Allen Farris & Warren King) -
The operational DADS system is now available for OTFC and appears to be working OK.
There is a serious bug in DADS 7.8.3 testing. A process is occasionally crashing in the ingest process due to an invalid pointer. The installation is on hold. OPUS 10.0 will be installed first.
DADS support for the two destination pipes: otfc and nonotfc needs to be supported by the time OTFC is released externally. The reason is that we need to maintain two separate otfc pipelines: a test and an operational system. Code is in place to do this, but is untested. Some enhancements are needed to the front-end of DADS. This capability will first be tested on the DADS test system.
Action Item: Allen and Joel will work this out for a future DADS release.
There was a problem with files not getting decompressed when requested from the archive. The files were sent to OTFC and failed calibration. Joel was unable to reproduce the problem.
-----------------------------------------------------
OPUS (Mike Swam) - The calibration pipeline is working on artichoke.
Mike is to develop the common rules system for OTFC. Bernie Shiao will develop the database layer for the OTFC interface.
Mike and Steve S. developed a draft of procedures for operators. Mike will distribute this to Tony and others.
Steve S. will give a demo of the procedures and the OMG.
Action Item: Based on the above, Tony will further develop procedures. -----------------------------------------------------
getref/upref (Bernie Simon) - Some fixes have been made to change SKIPPED to PERFORM for WFPC2 and a change for WAVECALS. These fixes are not yet installed. Some additional software changes are needed to handle database changes in DADS 7.8.3. A new getref/upref will be installed for that release.
There is a Y2K problem when upref writes FITS, due to IRAF. The FITS standard requires a 4-digit year, starting in 1999. However, either format can be handled by readers and writers. The next IRAF release will fix this problem. The behavior is produced by the FITS kernel, specifically the routine fxf_encode_date in fxf_encode.x. This problem should not cause a difficulty for OTFC and its users.
ACTION ITEM: Bernie will check with Phil Hodge about the meaning of SKIPPED for STIS. DONE (Skipped means perform.)
ACTION ITEM: Bernie will investigate getref/upref for time-tagged data.
ACTION ITEM: Bernie and Ed will investigate keyword placement for switches.
-----------------------------------------------------
Change System (Lisa Gardner, Steve Lubow, & Bernie Shiao) -
Scripts are handling the updating of the internal test system on ZEPPO to emulate the automated change system.
The automatic change system needs further development.
Action Item: Lisa is to develop support for the pending datasets table.
Melissa said that the last_catalog_date and last_software_date can be initialized for STIS to some recent past date.
ACTION ITEM: Lisa will set these dates for STIS as part of DADS 7.8.3.
Sylvia has provided an algorithm for determining the last_catalog_date and last_software_date for WFPC2. Steve L. has a script that determines the database updates that are required for the last_catalog_date. ACTION ITEM: Lisa will set these dates in DADS release 7.8.3.
-----------------------------------------------------
STIS (Bernie Shiao, Ed Hopkins, Melissa McGrath) -
Action Item: Lisa will install OKR entries in the dadsotfc database, after DADS 7.8.3.
Action Item: Bernie Shiao will investigate the level of effort required to retrieve the 2700 or so WAVECAL datasets. Lisa will determine the effort required to make the database changes and the ingest process changes for WAVCALs. Since there is no short-term need to change these values, this effort is of low priority.
-----------------------------------------------------
Testing (Melissa McGrath, Steve Lubow, Steve Slowinski) - This system now appears to work correctly. Little testing was done last week.
Random testing - Steve Lubow did some testing with mixed/proprietary data. The system performed correctly.
Regression and stress testing - Steve Slowinski reports continued problems with FTP in transferring data from DADS in a few precent of the cases. This is an unacceptable failure rate. The network configuration change did not help this problem. Tests by Mike Swam indicate various clues, but more work is needed to isolate the problem.
Action Item: Steve Slowinski will carry out stress tests, including the case of requesting corrupted data.
Action Item: Steve will work with the WFPC2 team to determine that the data are correct, based on their set of regression data. We need to have a standard set of results to compare against in an automated manner.
Sylvia and Faith are testing the consistency of newly calibrated data between the initial pipeline and OTFC.
Melissa finsihed identifying a set of STIS data for a regression test. This will be tested just after the installation of DADS 7.8.3.
Ed is working on a tool to handle differences between the initial pipeline and OTFC data. There may be a complication when the keyword placement goes into effect. Differences will appear.
