... Computerised Instrument Control and Data Acquisition (CICADA) is a software system for control of telescope instruments in a distributed computing environment. ... Computerised Instrument Control and Data Acquisition (CICADA) is a software system developed to provide access to, control of, and retrieval of data from, instruments mounted on observatory telescopes. ... Each instrument class generates its own request data structures using its own generate_req method, which is called by the control...

Next: Required observational data Up: File Formats Required Previous: CCD photometry . Every instrument seems to produce its data in a different format. However, it is relatively simple to re-format the data to a standard form; MIDAS table files are the obvious standard form to use. Usually the conversion is done in two steps: first reformat the existing data as an ASCII file with all records in the same format, and then convert this ASCII file to MIDAS table format. ...

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

Date: Sun, 28 Sep 2008 18:31:24 -0400 From: Rodger Doxsey Subject: HST safing last night Last night, the NSSC-I, and all the Instruments, were placed into safemode by the 486 (spacecraft) computer. ... At this point, it seems the problem is in the hardware located in a unit called the CU/SDF (Command unit/Science data formatter I believe). This unit is associated with the NSSC-I, and handles commands and telemetry functions between the NSSC-I and the instruments and the 486. ...
