Next: FITS data-types and Up: FITS Format Previous: FITS Format . A FITS file contains a sequence of logical header/data units (HDU) which all start with a set of header records describing the following data records. The logical record length of a FITS file is always 2880 bytes of 8 bits. Both header and data sections start in a new logical record. ... The basic FITS paper [ 1 ] specified both a logical and physical record length of 2880 bytes. ...

DIGITAL WDC EXCHANGE FORMAT . FOR OBSERVATORY 1.0 MINUTE VALUES 1. ... DATA-1 .. DATA-60 are 1-minute values of the given element for that hour. ... Typically, digital 1-minute values received by WDCs from organizations operating automatic magnetic observatory instruments are averages of more frequendy sampled values, e.g. 10-second point samples. ... If the method used to obtain 1-minute average values is important to a user, the WDC will assist in determining the exact procedure applied. ...

WDC-A Digital Exchange Format for One-Minute Geomagnetic Data (Update August 1993) 1. The logical record length is 400 coded characters containing header information, blank spaces, and data for one element for one hour. ... Each logical record contains header information and data in the following format: North polar distance, longitude, year, month, day, hour, element, observatory code, blank spaces, 60 data values, and an hourly mean. ... ORG is the origin of the data. A = Alaska Chain. ...

SAOtng supports display of photon event data contained in raw files, similar to its support for FITS Binary Table extensions (e.g., X-ray event lists). ... Because event files do not usually contain enough information to generate an image, we have adopted some conventions for specifying how to interpret the data in these files and for how to bin rows of events into images. To image an event file, it is first of all necessary to define the structure of the events in the event file. ...

... The information about how a hard disk has been partitioned is stored in its first sector (that is, the first sector of the first track on the first disk surface). ... The master boot record contains a small program that reads the partition table, checks which partition is active (that is, marked bootable), and reads the first sector of that partition, the partition's boot sector (the MBR is also a boot sector, but it has a special status and therefore a special name). ...
