IVM SPECIAL OBSERVATIONS DATA TAPES The times of each magnetogram/mosaic are available on SPAM. Tapes earlier than September 22, 1995 are not yet listed. The last special observation data tape was made 10 Oct 1997. The IVM single board computer failed on 28 Oct 1997. The replacement external computer, in use from 26 Jan 1998 to 16 Apr 98, was not programmed for recording to tape. The new external computer, part of the datasystem upgrade, records all observations to disk and they are included in the normal archive tapes beginning 17 Apr 1998. Special observation tapes were written in simple raw format. Each magnetogram is a separate tape file. The tape blocksize is 16384 bytes. To read one magnetogram, use the Unix command dd ibs=16384 if=/dev/rmt/Xn of=diskfile where the tape drive read is /dev/rmt/Xn and the disk file written is diskfile . All magnetogram files have a dual header, with 128 bytes of magic header, then 2048 bytes of OBLK header. The true filename is saved as ASCII in bytes 832 - 846 of the OBLK; it can be read and used to name the disk file correctly. _____________________________________________________________________________ XBP 092295 XBP/Cardinal Stripes 092395 Fila 092395 Fila 092495 Cardinal Stripes 101695 Cardinal Stripes 101795 Cardinal Stripes 101895 Cardinal Stripes 101995 Cardinal Stripes 102095 Cardinal Stripes 102295 Cardinal Stripes 102195 Cardinal Stripes 102395 Cardinal Stripes 102495 Cardinal Stripes 102895 (Includes Trans-equatorial Active Region scan) Cardinal Stripes 103195 Cardinal Stripes 121595 Cardinal Stripes 1 & 2 121995 Cardinal Stripes 122095 Cardinal Stripes 122195 Cardinal Stripes 122295 Cardinal Stripes 122395 Cardinal Stripes 122495 Flare Mode 010996 Fila 011196 Fila 011296 Fila 011396 Flare Genesis 1 & 2 011696 Flare Genesis 011896 Flare Genesis 012096 Cardinal Stripes 012996 Cardinal Stripes 020196 Cardinal Stripes 020296 Cardinal Stripes 020396 Fila 020796 Fila 020896 Cardinal Stripes 020996 Fila 021296 Fila 021396 Cardinal Stripes 022996 Cardinal Stripes 030196 Cardinal Stripes 030596 Cardinal Stripes 030896 Cardinal Stripes 030996 Cardinal Stripes 032096 Cardinal Stripes 032196 Flare Mode 032296 XBP 040896 XBP 040996 XBP 041296 XBP 1 & 2 041596 Cardinal Stripes 041696 Cardinal Stripes 042496 Fila 042496 Fila 042996 Fila 050396 Flare Mode 050996 includes partial mosaic Partial Mosaic 051396 Partial Mosaic 051496 Partial Mosaic 051596 Partial Mosaic 051696 AAP01 051796 XBP 052996 XBP 053196 Flare Mode 060696 Cardinal Stripes 061296 Cardinal Stripes 061396 Cycle sweep 061496 Cardinal Stripes 061996 Cardinal Stripes 062096 Cardinal Stripes 062196 Flare Mode 062696 Flare Mode 071796 Fila 050197 EFLX 050597 AR finescan 050997 AR finescan 051297 AR finescan 051597 XBP 051697 Cycle sweep 052097 Cycle sweep 052797 Cycle sweep 053097 MDI Campaign 081197 MDI Campaign 081297 MDI Campaign 081397 Cardinal Stripes 081897 Flare Mode 082997 XBP Campaign 090997 XBP Campaign 091097 HRTS Rocket Campaign 093097 Separators Campaign 100297 Separators Campaign 100697 Separators Campaign 100797 Separators Campaign 100897 Separators Campaign 101097 ______________________________________________________________________________ Last modified: Mon Sep 15 02:00:52 HST 2003
