First Observations of the New MEXART's Digital System

The data set contains the first observations of the new digital system of the Mexican Array Radio Telescope (MEXART).

Figure 05 data (20210202_032343-2b0.txt, 20210202_032343ch-181.txt, FIG05-20210202_032343-clean.txt) are Ascii files with two numeric columns of transit of Crab Nebulula during about 16 minutes, starting at 03:23:43 UT on February 2, 2021. The first column is the time-stamp with a time rate of 20 ms. The second column is the integrated flux power for each time. Each file has a different observing bandwidth. The file 20210202_032343ch-181.txt has a bandwidth = 24.4 MHz, and it was used to obtain the first row in Table 2. The file 20210202_032343-2b0.txt has a bandwidth = 2 MHz, and it was used to obtain the 2nd row in Table 2. The file FIG05-20210202_032343-clean.txt has a bandwidth = 12.5 MHz, and it was used sed to plot Figure 5.

The file FIG07-beam_20210130_220521.hdf5 has the observation of the transit of the Galaxy at 140~MHz detected with 64 latitudinal beams (each one having 512 frequency channels). The file is an HDF5 from April 10, 2021, the integration time is 1.5 s, 64 beams are recorded in 512 channels with a bandwidth of 12.5 MHz, the observation time was 23 hours and 56 minutes.

The file FIG09-3C48-08-04-2021_beam0.txt: integrated total flux @140 MHz, Source: 3C48 Date: 08-04-2021; Start time: 2021-04-08 19:11:06.362426, End time:   2021-04-08 19:21:53.270904, Column 1: yyyy-mm-dd, Column 2: HH:MM:SS, Column 3: AMPLITUDE, Integrated number of channels 430 out of 512. Bandwidth in MHz:  10.492
