While the Level 1 calibration can be applied to Level derived from quick look data, it is generally applied only to the LZ-derived FITS files. The calibration is still not final; however, it is possible to obtain calibrated images using reduce_level_bltadwin.ru in the LASCO section of the SolarSoft IDL library. Generate list of LASCO or EIT images based on search criteria: IDL list_of_fits_files = wlister() make_bltadwin.ru: Generate GIF files like the Realtime movies from a list of FITS files: IDL make_gifs,list_of_fits_files [,/pict,/tiff, ] lasco_bltadwin.ru: Read in EIT or LASCO or MK4 FITS file and puts header into a LASCO structure. LASCO Calibration Page. The calibrated (Level 1) C2 or C3 image can be generated using REDUCE_LEVEL_bltadwin.ru in the SolarSoft LASCO IDL library. The process is described here.. FITS keywords for the Level 1 product are here (PDF). Attitude and Time Correction.
LASCO and SolarSoftware Installation Guide. LASCO data are stored in FITS files.; The LASCO analysis sofware is written in the Interactive Data Language (IDL).; The LASCO software makes extensive use of the SolarSoftware (SSW) package. Mostly written in IDL, SSW provides a set of sofware libraries, databases, and system utilities which provide a common programming and data analysis environment. This wobble is due to the difference between the plane of the solar equator and the plane of symmetry of the F-corona. To view the MVI file you need to download one of the IDL movie routines, e.g. bltadwin.ru You will also need the IDL software, a commercial product from Research Systems, Inc. MByte MVI; MPEG (KByte). FITS stands for `Flexible Image Transport System' and is the standard astronomical data format endorsed by both NASA and the IAU. FITS is much more than an image format (such as JPG or GIF) and is primarily designed to store scientific data sets consisting of multi-dimensional arrays (1-D spectra, 2-D images or 3-D data cubes) and 2-dimensional.

The NRL LASCO Library of IDL procedures is available through the SolarSoft Library. Image Files. Level decompressed image files (FITS format) are available through the LASCO online database; Level 1 calibrated image files; These can be downloaded through the LASCO online database by selecting "level-1" as the file type. Note that this. While the Level 1 calibration can be applied to Level derived from quick look data, it is generally applied only to the LZ-derived FITS files. The calibration is still not final; however, it is possible to obtain calibrated images using reduce_level_bltadwin.ru in the LASCO section of the SolarSoft IDL library.
