LBA Disk Recorder Header Format DRAFT ATNF eVLBI Memo #3 Chris Phillips November 15, 2005 1 Introduction The LBA disk recorders currently use a very minimal header for recoded data files (a 16 byte string indicating the start time of the first data sample in the file). ... 2 Header Format The header will consist of a 4096 byte block of ASCII characters. ... Note that if a larger that 4096 byte header is used, the headersize keyword must be within the first 4096 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. ...

... NICMOS data are represented by five arrays for each readout. ... Samples array. ... Each downlinked readout is always represented by these five arrays ( Figure 13.4 ). Multiple readouts in the same dataset (e.g., MULTIACCUM data) are represented by repeated sets of these five arrays ( Figure 13.5 ). ... For data where multiple samples of the array were obtained during the integration, the samples array denotes the number of samples for each pixel in the corresponding science image. ...
