Computer Ephemeris. Second order reduction quantities. Explanations. This page consist of four little tables. First and second tables contains J a (in 0.000001 s ) and J d (0.0001") for nothern declination, third and fourth contains the same information but for southern declination. Each table have 13 informational columns headed with right ascension values, and some amount of rows, labelled with date. ...

... Instead, we only get timing information when data are dumped to the ground from the onboard computer from which we may infer when things happened. ... A UDL is always dumped from the spacecraft prior to the start of a science exposure, effectively flagging the start of the observation. ... For RAPID mode observations, the data are dumped as soon as they are taken. ... For ACCUM mode observations, a second UDL is dumped at the end of the exposure and prior to reading out any science data. ...

Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

Q: Are the magnitudes in the ETCs AB or Vega magnitudes? ... Q: How is the signal to noise defined? A: In optical and infrared imaging, the applications display a signal to noise over the PSF area, which is computed in a circle of radius seeing/plate_scale. ... In optical imaging only, a second signal to noise is computed which is the signal to noise at the central pixel. ... A: The template spectra stored in the database are measured or simulated spectra covering different wavelength range. ...

... For the HCTE the command first averages the rows given as the second parameter. The command uses the number of image pixels, the last image pixel and the first bias overscan pixel is obtained and computes the HCTE according to the formula: . where: bs are the counts above the bias level in the first overscan pixel in a row; ic are the count above the bias level in the last image pixel in a row; ni are the number of image pixels in a row. ...
